Is the Google Search for internal enterprise knowledge finally here...but from OpenAI? It certainly seems that way. Today, OpenAI has launched company knowledge in ChatGPT, a major new capability for subscribers to ChatGPT's paid Business, Enterprise, and Edu plans that lets them call up their company's data directly from third-party workplace apps including Slack, SharePoint, Google Drive, Gmail, GitHub, HubSpot and combine it in ChatGPT outputs to them. As OpenAI's CEO of Applications Fidji Simo put it in a post on the social network X: "it brings all the context from your apps (Slack, Google Drive, GitHub, etc) together in ChatGPT so you can get answers that are specific to your business." Intriguingly, OpenAI's blog post on the feature states that is "powered by a version of GPT‑5 t…

Microsoft today held a live announcement event online for its Copilot AI digital assistant, with Mustafa Suleyman, CEO of Microsoft's AI division, and other presenters unveiling a new generation of features that deepen integration across Windows, Edge, and Microsoft 365, positioning the platform as a practical assistant for people during work and off-time, while allowing them to preserve control and safety of their data. The new Copilot 2025 Fall Update features also up the ante in terms of capabilities and the accessibility of generative AI assistance from Microsoft to users, so businesses relying on Microsoft products, and those who seek to offer complimentary or competing products, would do well to review them. Suleyman emphasized that the updates reflect a shift from hype to usefulnes…

May Habib, co-founder and CEO of Writer AI, delivered one of the bluntest assessments of corporate AI failures at the TED AI conference on Tuesday, revealing that nearly half of Fortune 500 executives believe artificial intelligence is actively damaging their organizations — and placing the blame squarely on leadership's shoulders. The problem, according to Habib, isn't the technology. It's that business leaders are making a category error, treating AI transformation like previous technology rollouts and delegating it to IT departments. This approach, she warned, has led to "billions of dollars spent on AI initiatives that are going nowhere." "Earlier this year, we did a survey of 800 Fortune 500 C-suite executives," Habib told the audience of Silicon Valley executives and investors. "42% …

In a striking act of self-critique, one of the architects of the transformer technology that powers ChatGPT, Claude, and virtually every major AI system told an audience of industry leaders this week that artificial intelligence research has become dangerously narrow — and that he's moving on from his own creation. Llion Jones, who co-authored the seminal 2017 paper "Attention Is All You Need" and even coined the name "transformer," delivered an unusually candid assessment at the TED AI conference in San Francisco on Tuesday: Despite unprecedented investment and talent flooding into AI, the field has calcified around a single architectural approach, potentially blinding researchers to the next major breakthrough. "Despite the fact that there's never been so much interest and resources and …

One of the leading architects of the current generative AI boom — Microsoft CEO Satya Nadella, famed for having the software giant take an early investment in OpenAI (and later saying he was "good for my $80 billion") — published his latest annual letter yesterday on LinkedIn (a Microsoft subsidiary), and it's chock full of interesting ideas about the near-term future that enterprise technical decision makers would do well to pay attention to, as it could aid in their own planning and tech stack development. In a companion post on X, Nadella wrote, “AI is radically changing every layer of the tech stack, and we’re changing with it." The full letter reinforces that message: Microsoft sees itself not just participating in the AI revolution, but shaping its infrastructure, security, tooling …

rxResource — from request/loader to params/stream Angular 20 ships a refined Resource API. If you used resource()/rxResource() in v19, two names changed and status got simpler: request → params loader → stream (used for both querying and streaming) ResourceStatus → string union ('idle' | 'loading' | 'reloading' | 'resolved' | 'error') This post is a hands‑on guide to querying/paginating data with rxResource in Angular 20 using Signals, with typed results, status UIs, and a one‑file demo you can paste. import { rxResource } from '@angular/core/rxjs-interop'; const pageRef = rxResource({ params: () => queryParams(), // reactive input (was `request`) stream: ({ params, abortSignal }) => // Observable/Promise factory (was `loader`) http.get('/api/it…  ( 9 min )

AI won’t replace QA — but QAs who use AI will replace those who don’t. 💬 Why this matters A few years ago, “AI in testing” sounded futuristic. As a QA Lead, I see a clear difference between testers who leverage AI and those who ignore it. And honestly — when we hire new QAs, I always pay attention to how candidates talk about AI. 🧠 1. Prompting as a core QA skill Prompting is basically asking better questions — but to AI. Why it matters: 1. Generate test cases from user stories 2. Translate acceptance criteria into concrete scenarios 3. Explore “what if” or edge cases quickly Example prompt: “Act as a senior QA. Generate 10 edge-case test scenarios for a signup form with CAPTCHA and rate-limiting.” 🪄 Tip: Always use context. Don’t just ask “generate test cases” — tell the AI what envi…  ( 8 min )

Decision Trees Evolved: Faster, Smarter Reinforcement Learning Imagine a self-driving car hesitating at a complex intersection or a robotic arm fumbling with a delicate task. Complex AI making suboptimal decisions? Current reinforcement learning often struggles to deliver both optimal performance and easily understandable decision-making, especially as problem complexity grows. What if we could unlock clear, high-performing policies with a radical speed boost? At its heart, this involves finding the best if-then-else structure, essentially a decision tree, that guides an agent through different states to maximize rewards. Optimizing decision trees within a dynamic environment is traditionally computationally expensive. The breakthrough lies in reframing the tree's construction as a very…  ( 7 min )

According to a Software Engineer Who Landed 5 Tech Offers from FAANG and Unicorn Startups. When applying for my first software engineering role, I sent out 367 cold emails and LinkedIn messages. This resulted in 21 technical phone screens and ultimately five full-time offers from companies like Meta, Stripe, and three high-growth startups. However, most of those interviews only materialized after I started doing two crucial things: first, extensive networking with engineering managers, tech recruiters, and developers already working at my target companies; and second, completely revamping my resume based on their insider feedback. Here are the five biggest resume mistakes I identified, along with the changes needed to maximize your chances of landing that first technical interview. While y…  ( 8 min )

The Border Gateway Protocol serves as the Internet's primary routing mechanism, operating through interconnected relationships between network devices. At the core of BGP functionality lies the concept of peering relationships, where routers establish connections to share routing data across different networks. These BGP peer connections determine how internet traffic flows globally, affecting everything from connection speed to network costs. Effective monitoring of these peer relationships requires understanding session stability, route exchanges, and potential security vulnerabilities. Network operators must implement comprehensive monitoring strategies that go beyond basic connectivity checks to ensure optimal performance and detect issues before they impact users.

You’ve prompted your large language model, a powerhouse of digital intelligence, to perform a task so simple a child could do it: “Write a short poem and save it to my desktop as poem.txt.” The AI obliges, composing a beautiful stanza in seconds. It presents the text to you in a pristine, ephemeral output window. You copy it, open a text editor, paste the content, and save the file yourself. The AI, for all its cognitive might, remains trapped behind the glass of its application, unable to touch your actual computer. This is the frustrating paradox of modern AI assistants. They possess immense knowledge but lack basic agency. They can reason about your file system but can't interact with it. They are brilliant minds suspended in a digital void.

I was on my phone, which wasn’t very convenient, and every website was different — so I quickly got frustrated. This situation happened a few times, and then I realized I could make this task easier by creating a small app to check court availability for me. It seemed like a good small project. I have two small kids, so I don’t have much free time, but I decided to spend 15–30 minutes on it whenever I could — and here we are!

A System API should only connect to one System of Record. A System API is meant to be a clean layer of abstraction over a single data source. This one-to-one relationship makes your architecture clearer and more flexible: Focus and simplicity: the API clearly shows a single source, which makes it easier to understand where data comes from and how it is structured.

Let’s unpack the tools that can safeguard your systems — and the ones cybercriminals are now using against you. AI-driven security tools are becoming smarter and faster than ever. They detect unusual patterns, block suspicious activity, and even learn from past attacks. Here are a few worth keeping on your radar: Tools like Darktrace and Cylance use machine learning to study your normal network behavior. When something unusual happens — like a massive data upload at 2 a.m. — they instantly flag or block it. AI filters in Microsoft Defender and Proofpoint now identify phis…  ( 7 min )

Read our original blog here We rebuilt onboarding around our MCP (Model‑Context‑Protocol) integration so developers start inside their editor with our SDK—not a detour through example apps or sandboxes. Early results: ~3× more users reach SDK install versus our previous flow, and they see real product value sooner. This piece shares why we made the change, how the MCP‑centered flow works, what we learned, and what’s next. Our north star for onboarding has always been simple: get users to the “aha” moment fast. With a SDK‑based product, that “aha” usually requires installing the SDK into the user’s own app—and that’s exactly where friction creeps in. We had invested heavily in a guided tutorial with three flavors: No‑code, in‑browser walkthrough Code sandbox to see real code without install…  ( 10 min )

After 25 years navigating the wild west of digital security and building systems from scrappy startups to global enterprises, I've learned one undeniable truth: complexity is the enemy of both security and transparency. The digital divide isn't just about internet access; it's about digital trust. At BetterGov.ph, we're building the infrastructure of transparency, proving that open-source solutions, grounded in DevSecOps principles, can transform our government for the better, making it more resilient and auditable [2]. For too long, our government has been shackled by expensive, proprietary software that promises a lot but often delivers opacity and vendor lock-in.

Intro Hi, guys! In this post we're going to talk about Next.js routing. This time we will only cover the core concepts of routing and in another post we will learn more about advanced concepts for a complete guide. In this guide I am going to use TypeScript. If you use JavaScript, just remove the types where necessary. The Core Route Files Dynamic Routing Typescript Helpers To define routes in Next.js, we use file-system based routing, which mean we use files and folders from within our app. When installing the Next.js app using: npx create-next-app@latest Next.js will create a folder app. You can safely delete everything inside it to remove the noise. This is of course not necessary, but I recommend doing it just to see every file in action without those boilerplate code from Next.js.…  ( 11 min )

If you’ve ever heard that “Java supports only single inheritance”, you might think Java is limited compared to languages like C++ that allow multiple inheritance. But the truth is... Java gives you the best of both worlds — simplicity and flexibility — without the messy diamond problems. Let’s break it down 👇 🧩 What Is Inheritance in Java? Inheritance allows one class to acquire the properties and behaviors (fields and methods) of another. It’s one of the core pillars of Object-Oriented Programming (OOP). class Animal { void eat() { System.out.println("Eating..."); } } class Dog extends Animal { void bark() { System.out.println("Barking..."); } } public class Main { public static void main(String[] args) { Dog d = new Dog(); d.eat(); …  ( 7 min )

One of the cool things about the way we've architected Hypertune is that experiments aren't something you reference directly in your code. Instead, they're created in the Hypertune dashboard and inserted into the rollout logic of a feature flag. Many teams manage feature flags and experiments separately, often using different systems for each. As a result, they end up with separate “experiment flags.” When testing a new feature, that means checking two flags in code: Your main feature flag — to control rollout to internal users, beta testers, etc. Your experiment flag — to split traffic between variants. At first, this might seem reasonable. But it quickly introduces complexity — and risk. In theory, the experiment flag should only be checked if the main flag is true. A user should only en…  ( 7 min )

I’ve always loved both maths and coding, but I never found a space where the two truly merge. So I decided to build one myself: MathHacks. It’s a weekend “mathathon” where participants build creative maths-based projects — visualisations, puzzles, small tools, or any idea that blends maths and creativity. Think of it as a hackathon, but for maths. The first MathHacks starts in 8 days and it’s completely free and open to everyone — students, developers, or anyone who enjoys problem-solving. Why I built it: I wanted a place to experiment with maths in a fun, hands-on way. I wanted something that feels creative, not competitive. I wanted a small, community-driven space for maths + coding lovers. If that sounds like your kind of weekend, come join in at the first mathathon I’d love to see what you come up with!  ( 6 min )

Introduction I found a way to avoid the well-known problem where “infinite scroll resets after a browser back,” using a modal that combines Next.js App Router’s Intercepting Routes and Parallel Routes. Even after using the browser back action, the scroll position of the infinite list is preserved. You can try it yourself with this demo app. This is a Next.js framework–specific approach, but I hope it helps anyone who is facing—or has faced—this problem. Notes This post does not explain the low-level details of Intercepting Routes or Parallel Routes. The main goal is to convey how the app feels when infinite scroll is combined with a URL-addressable modal built with Intercepting + Parallel Routes, via the demo app. The context is a web application, not a native app. Infinite scroll UIs h…  ( 10 min )

​FastAPI is getting more and more popular, as is building agents. Developers building agentic systems are starting to turn to FastAPI as one of the more ergonomic web frameworks for building endpoints and then adding on a Model Context Protocol (MCP) layer so that AI agents can discover and invoke those endpoints as “tools”. For example, with FastAPI-MCP you can take an existing FastAPI application, attach mcp = FastApiMCP(app) and mcp.mount(), and your endpoints become usable by an LLM-based agent with minimal extra work. But when it comes time to deploy your agent, how should you go about it? TL;DR: Heroku is great to start, but you pay for convenience with higher tiers, less control, and platform lock‑in. Defang keeps the Heroku‑like workflow but deploys your FastAPI app into yo…  ( 9 min )

In modern data workflows, APIs are everywhere — powering everything from model inference to data extraction. Yet, handling API failures gracefully is often neglected by data scientists, who tend to focus on analysis and modeling while treating fault tolerance as a “software engineering problem.” However, failure handling is not just an engineering nicety — it’s what makes a data pipeline resilient, automated, and production-ready. When your data pipeline processes hundreds or thousands of files via APIs, a single timeout or upload error can halt the entire process. You depend on external systems — their uptime, latency, and error messages are outside your control. Failures aren’t binary — some require retries, others should be skipped or gracefully degraded.

If you’ve ever watched your site slow down under traffic or worse—collapse during a peak moment—you’ve felt the sting of inadequate performance testing. But what kind of test would have saved you? Load or stress? And why does it matter? This isn’t just a definition battle. It’s about making the right calls across your dev, QA, and SRE teams.

Erase and Evolve: Selective Amnesia for Ethical Graph Neural Networks Imagine your AI stubbornly promoting outdated or biased information. Re-training from scratch is costly and inefficient. What if you could selectively erase unwanted knowledge from its memory, like deleting specific nodes from a social network without affecting the overall structure? That's the promise of graph unlearning. It's about surgically removing the influence of specific data points or connections in a graph neural network (GNN) without drastically impacting the model's overall performance or requiring a complete retraining. The key is to strategically "forget" information by focusing on the influence of connections, prioritizing the removal of high-impact edges.

Getting data from modern websites is not the same as it used to be- today, most websites render their data dynamically making it hard for traditional web scrapping tools to obtain any data. In this project: The Africa Energy project, we are going to use different tools to obtain data about Energy Indicators across 54 African countries for the years 2000 - 2022 from the The Africa Energy Portal. The project features: a web scrapper that extracts JSON data from API network responses. The Africa Energy Portal is a dynamic webpage that contains information about energy indicators across 54 African countries. The indicators are energy access, supply and technical aspects related to energy. The indicators are further broken down into sub-sectors such as 'Population access to electricity-National' which shows the percentage of people with access to electricity on a national level etc. The project uses the following technologies: a. Python for developing the web scrapping logic The scrapper utilizes Selenium to automate browser interaction such as loading the page and selecting all required themes, years and countries for precise data extraction. The scrapper obtains all the selected fields of the data ie; id, name, score, unit, region name, indicator topic, indicator source, indicator name, indicator group, year, url The data is extracted in JSON format and appended to an empty list before it is flattened and converted to csv format. Working on this project has been nothing short of a learning experience from the thought process of understanding the project, to learning of different ways to execute the project, to implementation of the same.

In the absence of something like Immer, if you need to immutably update a deeply-nested object, you can do this: const properties = { /* ... */ }; setTracks((prev) => ({ ...prev, [trackId]: { ...prev[trackId], points: { ...prev[trackId].points, [pointId]: { ...prev[trackId].points[pointId], properties: { ...prev[trackId].points[pointId].properties, ...properties, } } } } })); Or you can do this: setTracks((prev) => merge({}, prev, {[routeId]: {points: {[pointId]: {properties}}}})) );  ( 6 min )

This is a submission for the 2025 Hacktoberfest Writing Challenge: Open Source Reflections This year, I had the pleasure of participating in Hacktoberfest 2025, and it was an exciting journey that provided me with valuable experiences and insights into the world of open-source development. Here's my reflection on the highs, lows, and everything in between. During Hacktoberfest, I contributed to multiple projects, but one that stood out was my repository, LeetCode in PHP. The repository focuses on solving LeetCode problems using PHP, and it’s been a rewarding experience maintaining it. I got to not only solve algorithmic challenges but also improve my PHP skills and learn new optimization techniques. The most exciting part of Hacktoberfest was seeing how open-source contributions can make a…  ( 8 min )

I didn’t set out to join a fandom. I played a game. I enjoyed it. That was supposed to be the end of it. But then I finished the second episode of Dispatch by Adhoc Studio and sat there, still in the glow of it, and realized something was pulling at me. A kind of emotional inertia. Yes, the writing was immaculate, yes the mechanics were smoothly executed. But more than that, I cared. About my decisions, about the characters and...I wanted to talk about them. I wanted to know what other people saw in them. I wanted to laugh at the same dumb lines and ache at the same quiet moments That’s when it clicked: this is what makes someone a fan. Not how many hours you’ve logged or how much merch you own. Just this: you care so much that the silence after the credits rolls feels too loud. And the …  ( 7 min )

If you’ve ever pushed a bug to production (and who hasn’t?), you know that cold sweat moment when an error alert hits your Slack at 2 AM. Debugging in production isn’t like fixing code on your laptop — there’s pressure, limited visibility, and real users depending on you. But with the right mindset and tools, you can handle it without breaking more things. Let’s walk through a safe and strategic way to fix production issues — step by step. Your logs are your first line of truth. Before touching the code or restarting anything, observe what’s actually happening. ✅ Tips: Filter logs by request ID, timestamp, or user session. Look for error patterns — repeating exceptions, failed API calls, or database connection errors. Avoid drowning in noise: focus on recently changed modules. …  ( 7 min )

Task 2: Array Formation The Task You are given two lists: @source and @target. Write a script to see if you can build the exact @target by putting these smaller lists from @source together in some order. You cannot break apart or change the order inside any of the smaller lists in @source. Example 1: Input: @source=([2,3], [1], [4]), @target=(1, 2, 3, 4) Output: true Use in the order: [1], [2,3], [4] Example 2: Input: @source=([1,3], [2,4]), @target=(1, 2, 3, 4) Output: false Example 3: Input: @source=([9,1], [5,8], [2]), @target=(5, 8, 2, 9, 1) Output: true Use in the order: [5,8], [2], [9,1] Example 4: Input: @source=([1], [3]), @target=(1, 2, 3) Output: false Missing number: 2 Example 5: Input: @source=([7,4,6]), @target=(7, 4, 6) Output: true Use in the or…  ( 9 min )

I released @acoolhq/react-tiny-store. It is a small external store that works with useSyncExternalStore, is hydration-safe, and keeps re-renders scoped with selectors. npm i @acoolhq/react-tiny-store I needed something between raw Context and a full-blown state library. Context + reducers made unrelated components re-render whenever a big object changed, and pulling in Redux/Zustand felt like overkill for a few shared slices. You want fine-grained renders without heavy setup. You have a few shared slices and don’t want a large framework. You care about SSR correctness with minimal API surface. A full-featured global state framework with time-travel and middleware. It’s a small, practical layer for the 80% case. Selector-based reads so only affected components re-render Works with SSR hydr…  ( 7 min )

TL;DR Hybrid work is here to stay, but thriving in it requires a deliberate mix of technology, culture, and soft‑skill development. This guide walks you through the current hybrid landscape, shows how to build a robust communication framework, cultivates trust, aligns productivity processes, and highlights practical ways to upskill your team—including a quick look at tools like softskillz.ai for targeted coaching. When the pandemic forced many companies to go fully remote, most organizations discovered that a binary “office vs. home” model was too limiting. The hybrid work model—where employees split time between a physical office and remote locations—offers flexibility, broader talent pools, and often higher employee satisfaction. Yet it also introduces friction points: misaligned expec…  ( 12 min )

Why Interoperability Matters in Healthcare? For example, a patient visits a primary care doctor, is referred to a specialist, goes in and out of lab visits, and then winds up in the emergency room. Each provider collects information. But if their systems do not talk to each other, important information can be overlooked. That can result in repeated tests, delayed diagnoses, or even dangerous errors. EHR, LIS), smart connected devices, and the user interfaces for patients and medical staff.(Source: ScienceSoft) Improved decisions around care: Physicians can view their full patient history instead of fragmented bits.

The concept of the T-shaped engineer isn't new. It's been around, quietly championed by forward-thinking tech leaders and organizations. But in 2025, as LLMs transform how we build software, this professional archetype has evolved from "nice to have" to essential. Picture the letter T. The horizontal bar represents breadth - a working knowledge across a wide range of technologies, methodologies, and domains. The vertical stem represents depth - expert-level mastery in one or a few specific areas. A T-shaped engineer might have deep expertise in distributed systems architecture while maintaining conversational fluency in frontend frameworks, DevOps practices, data engineering, and security principles. They can collaborate meaningfully with specialists across disciplines because they underst…  ( 7 min )

I recently attended GOTO conference in Copenhagen (https://gotocph.com/2025, you can find the slides for some of the presentations there) and would like to share some of the interesting topics. This is about organisations, but I think it has even wider application. There are 2 types of organisations which differ only by the answer to the question: are people bad or good? These 2 approaches can be seen in my opinion everywhere when there is a group of people which need to follow any rules. This can be for example how the city authorities deal with passengers as far as transportation is concerned. However, the forest is rare. There are also quite many desert people who like the yellow and in fact most of the organisations are like Sahara. I think the key is just to realize these 2 landscapes exist and know which one suites you best to be able to work effectively. https://tidyfirst.substack.com/p/forest-and-desert https://martinfowler.com/bliki/ForestAndDesert.html  ( 6 min )

Last month I was joking with a friend about possibly traveling to Bali in December. I didn’t search it, didn’t message anyone about it, and didn’t even type the word “Bali” anywhere on my phone. And yet — the next day my Instagram Reels were full of Bali travel videos. Coincidence? Or does Instagram secretly listen to us through our phones? This question — “Is Instagram listening to me?” — pops up in conversations everywhere. The short answer: almost certainly not in the way people imagine. But the full answer needs a look at how recommendation systems work, why coincidences feel eerie, and what data apps do have access to. How recommendation engines predict what you want to see Instagram’s feed and Reels recommendations are powered by machine learning models that examine a lot of signals.…  ( 7 min )

The concept of autonomous agents, software that can operate, transact, and make decisions on-chain without constant human supervision has been around for a while. However, widespread adoption has been hampered by incompatible frameworks, isolated registries, and trust assumptions. ERC-8004 is a proposed Ethereum standard designed to address these challenges by providing a minimal yet extensible framework for agent discovery and trustless interaction. The standard defines three core registries: Identity: Assigns each agent a unique ID and links it to off-chain metadata describing capabilities, supported protocols, and domains. Reputation: Creates an on-chain audit trail of client-authorized feedback, enabling reputation tracking without storing all data on-chain. Validation: Supports task …  ( 7 min )

A Usabilidade para além do Front-end Quando falamos em "usabilidade", é quase automático pensarmos em interfaces bonitas, botões no lugar certo e telas que respondem rapidamente. Em resumo: a experiência do usuário final. Mas e se eu disser que a usabilidade é um conceito que deveria ser aplicado muito antes do front-end? Que ela começa no coração do sistema: o back-end. Um back-end com boa usabilidade não é sobre ter uma "interface gráfica bonita" (afinal, o "usuário" aqui é, na maioria das vezes, outro desenvolvedor ou sistema). É sobre criar uma experiência fluida, intuitiva e eficiente para quem vai consumir, manter e expandir o seu código. Pense no back-end como a cozinha de um restaurante.

Oasis, the team behind the Sapphire confidential EVM, has launched what might be one of the boldest blockchain security experiments in recent years: a public challenge to break their TEE-based system. There’s one Bitcoin (wBTC) locked in a Sapphire smart contract. If anyone can extract the private key controlling it, the funds are theirs. No bug report. No triage. Just proof through action. The setup is simple but powerful: a smart contract deployed on the Sapphire Mainnet generates a keypair entirely inside an Intel SGX enclave. The private key never leaves the TEE, never exists in plaintext, and has no API or function that can export it.

But I thought I'd put together a Quickfire article about it to help spread the word, for anyone (such as those new to PHP) who may not be aware of it. match Expression in PHP The match expression allows you to compare a value against multiple conditions and return a given result (although a result doesn't necessarily have to be returned). It's similar to a switch statement in the sense that you can define "branches" based on different conditions.

Today I finally understood what makes React so powerful — state. Once you realize that your UI is just a reflection of state, React suddenly clicks. I created a small component that shows three steps: Learn React ⚛️ Apply for jobs 💼 Invest your new income 🤑 It includes “Next” and “Previous” buttons to move through steps, and a close button to hide the section. useState, I learned how to control what appears on screen based on the component’s state. Update State Based on Current State When updating a value using its previous value, always pass a function to the setter: setStep((s) => s + 1); That ensures React always uses the latest version of state — even with multiple updates. One Component = One State Every component has its own state — completely independent from others. UI as a Function of State The best way to think about React is: 🖥️ UI = f(state) Whenever your state changes, React re-renders the UI to match. When to Use State Use useState for data that should change over time or control the UI, like: Whether a modal is open Which step the user is on A toggle or input field If a value doesn’t affect what the user sees, use a normal variable instead — not state. 👉 Use state for anything dynamic. Understanding state changed the way I see React. thinking in terms of state transitions. Now, every time I build something dynamic, I ask myself: “How should my component look when this piece of state changes?” And that’s when React truly starts to feel alive. ⚡ I’ll keep experimenting with multiple states in one component and later explore Context and Reducers to manage complex state.  ( 7 min )

In previous posts, I’ve introduced some of the key syntax and features of Turbine, a Markdown-inspired scripting language. out parameter, a mechanism for returning multiple values from a function, similar to how C and C++ handle it. In Turbine, a function can only have one return value. But sometimes, you want to return a main result and an additional status flag, for example, when you want to detect division by zero in a divide() function. Many scripting languages, such as Python, can easily return multiple values using tuples: def divide(a, b): if b == 0: return 0, False return a / b, True result, ok = divide(10, 2) That’s convenient and expressive. references or pointers to return additional results: int divide(int a, int b, bool &ok) { if (b == 0) { ok = f…  ( 8 min )

While the agent performed well in some cases, my last post outlined a number of ways in which it fell short. This final post is written more from my educator perspective, and shares my lessons learned about AI in student assessment. Although this has shown that AI agents should NOT score student assessments, I also share some new directions in which this type of tool could be appropriate and helpful. This was highlighted in my last post, so I will not repeat the evidence here. I am admittedly an AI skeptic in regards to education, so this lesson is not at all surprising to me. Hallucinations generated by the LLM are the biggest concern…  ( 11 min )

They don’t tell you this in bootcamp, but coding is basically emotional damage with syntax. 😅 One minute you’re like: “I’m a genius — I just solved a bug!” And the next minute you’re like: “Why is this semicolon ruining my entire life?” Let’s be real — we’ve all been there. Coding isn’t just about logic, it’s about emotional resilience. You’re not just building software — you’re building character. 😂 Here’s the truth nobody says out loud: Even the best developers Google the same question five times a day. We all copy-paste from Stack Overflow like it’s a sacred ritual. We all say “just one last test” 47 times before pushing to production. But here’s the beauty in it — Coding teaches you how to keep trying even when nothing works. It teaches you patience, problem-solving, and humility. And sometimes… it teaches you new swear words. 💀 So if you’re feeling stuck or frustrated, remember — every great developer once broke down over a missing bracket. The difference between junior and senior isn’t how much they know — it’s how calmly they panic. 😎 💬 What’s your funniest “coding meltdown” moment? Drop it below — let’s laugh (and cry) together. 👇  ( 6 min )

Welcome back to Day 3 of our DSA Problem Series, where we explore one problem each day, understand its logic, and break it down into clean Java code.

Are your files and folders missing after you run the newly created image? This is a common issue when building images with Packer. It is a widely used tool for creating machine images in a repeatable and automated way. When using the QEMU builder to generate local or CI-friendly images, it's common to upload files with the file provisioner and configure systems using shell provisioner. One often overlooked but critical part of this workflow is how the virtual machine shuts down after provisioning. Without a proper shutdown, the resulting image can be unstable, incomplete, or even unbootable. graceful shutdowns matter. After provisioning completes, Packer snapshots the virtual disk to produce the final image. If the guest operating system is not properly shut down before this snapshot, yo…  ( 7 min )

Introduction In cloud environments, organizations often segment their IT infrastructure into multiple virtual networks (VNets) for better security, performance, and management. For instance, a company may separate core IT services such as DNS and security from departmental workloads like manufacturing or R&D. However, in many cases, applications and services across these networks still need to communicate securely for example, when a manufacturing app needs to access a shared DNS or authentication service hosted in the core network. This is where Azure Intersite Connectivity comes in. By implementing Virtual Network Peering, you can connect multiple VNets in Azure, allowing traffic to flow privately through Microsoft’s backbone network without requiring VPNs or gateways. In this hands-on…  ( 8 min )

Every click, swipe, and voice command that feeds into artificial intelligence systems passes through human hands first. Behind the polished interfaces of ChatGPT, autonomous vehicles, and facial recognition systems lies an invisible workforce of millions—data annotation workers scattered across the Global South who label, categorise, and clean the raw information that makes machine learning possible. These digital labourers, earning as little as $1 per hour, work in conditions that would make Victorian factory owners blush. These workers make 'responsible AI' possible, yet their exploitation makes a mockery of the very ethics the industry proclaims.

Introduction In the part 1 we introduced our sample application. We basically used AWS Lambda Functions like GetProductByIdHandler where we extended io.micronaut.function.aws.MicronautRequestHandler and injected DynamoProductDao and other services by using Jakarta EE jakarta.inject.Inject annotation. While this is a valid approach, sometimes you have existing Micronaut REST application which runs on containers or servers, and you'd like to port it to Serverless with as little effort as possible. As we use here DynamoDB we're locked-in, so it's more about making our application portable between AWS services like EC2, ECS (also with Fargate), EKS (also with Fargate) and Lambda. Of course, you can replace DynamoDB repository layer with RDS, Aurora, Aurora Serverless or newly released Aurora…  ( 12 min )

Unlocking AI: The Simplicity Revolution in Reinforcement Learning Tired of reinforcement learning (RL) models that feel like black boxes? Do you dream of AI that not only performs well but also explains why it made a particular decision? Current RL approaches often involve complex neural networks, making it tough to understand their logic and adapt them to new situations. Imagine you want to teach an AI to navigate a complex maze. Traditionally, this meant training a neural network for countless iterations, with little insight into the strategy it was developing. A new approach uses decision trees directly as policies. This leads to interpretable rules, like "if the corridor is clear, move forward, else check for an opening to the left". Optimizing these tree-based policies efficiently, …  ( 7 min )

Welcome to Day 12 of the #80DaysOfChallenges journey! After chasing the longest word in a sentence on Day 8, today's challenge, finding the longest word without using len(), took things to a new level. This beginner-friendly task pushed me to rethink a familiar problem, diving deeper into manual counting, loops, and logic. It's like solving the same puzzle but with a twist that forces you to understand the gears behind Python's built-in tools. The goal was to find the longest word in a user-provided sentence, but with a catch: we can't use Python's len() function to count characters. Instead, we manually count each word's characters using loops, returning both the longest word and its length as a tuple. This challenge was a fantastic exercise in manual iteration, string manipulation, and l…  ( 10 min )

Email is still a crucial communication medium for companies, but it also ranks among the top platforms targeted by cybercriminals. Scams such as phishing, spoofing, and business email compromise (BEC) lead to financial losses in the billions for businesses annually. To combat these risks, implementing email authentication protocols like DMARC has become vital for safeguarding domain reputation and ensuring trustworthiness. DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is a protocol designed to help domain owners stop unauthorized usage of their email domains. It operates by confirming whether an email that appears to originate from a specific domain is actually sent by authorized servers. If the verification fails, the email can either be rejected…  ( 8 min )

I'm currently working on a software designed more than a decade ago. It offers a plugin architecture: you can develop a plugin whose lifecycle is handled by the software. The tough part, though, is how you access the platform capabilities: via static methods on singletons. @Override public boolean start() { var aService = AService.getInstance(); var anotherService = AnotherService.getInstance(); // Do something with the services var result = ...; return result; } There's no easy way to test the start() method. In the old days, Mockito developers had pushed back against this feature, and the only alternative was PowerMock. The decision was reversed in 2020 with the 3.4.0 release, which introduced static method mocking in Mockito. I liked the previous situation better. M…  ( 7 min )

An exception is an unwanted or unexpected event that occurs during the execution of a program (i.e., at runtime) and disrupts the normal flow of the application. Java Exception Handling is a way to detect, handle, and recover from unwanted or unexpected events (exceptions) that occur during the execution of a program. It allows the program to deal with runtime errors gracefully, without crashing, by providing alternative flows or meaningful error messages. Example: Imagine you’re using a food delivery app. You place an order, but your internet disconnects for a moment. Instead of crashing, the app shows a message: "No Internet Connection. Please try again." This is possible because of exception handling. The app catches the error and shows a friendly message instead of terminating . An…  ( 9 min )

After seeing an example on cassidoo's site, I decided to add an "AI Transparency" page to my site as well. Both she and the post she links make a really good point about how, if a person or company is transparent about how they use AI, it helps us trust that their work is more authentic in general. They recommend adding a page to your site (e.g. /ai) that details how you make use of generative AI (or not). From the simplest "No posts on this site are written with generative AI," to a longer, more detailed breakdown, the idea is not to cover your bases with legalese, but to be authentic, clear, and real. It's not a bad thing to use AI, necessarily. It's a tool like any other, and a user needs to understand how it works--pro's, con's, strengths, and dangers. But it's good to be open about it to help people understand and gain context for your work. And if you do decide to add one to your site, you can add your site to this public database of /ai page-having sites!  ( 6 min )

Three years ago, I started the Japanese Property Price Forecasting project to analyze and predict second-hand apartment prices in Japan. It was a great learning experience, but like many early projects, it lacked a structured pipeline and modern machine learning best practices. Recently, I revisited the notebook and modernized the workflow. Here’s what I added and improved. Previously, the notebook handled categorical and numeric features manually. Now, it uses a full scikit-learn Pipeline to cleanly separate numeric and categorical preprocessing: Numeric features: imputation with mean + standard scaling Categorical features: imputation + one-hot encoding (handling unknown categories safely) This makes the workflow cleaner, easier to maintain, and fully reproducible. Instead of a simple regression, the updated notebook uses LightGBM with hyperparameter tuning. This allows the model to achieve better performance while keeping the training process efficient. Old column names had spaces and special characters, which could cause issues with pipelines. All columns are now sanitized (_ instead of spaces and symbols), making the notebook pipeline-friendly and more robust for experimentation. The notebook now loads CSVs dynamically, making it easy to handle multiple files without hardcoding paths. Updating old projects is a great way to apply what you’ve learned over time. In this case: Cleaner, maintainable code Better reproducibility Stronger model performance Ready for future extensions (feature engineering, explainability, or deployment) You can explore the updated notebook here: Japanese_Property_Price_Forecasting_v2.ipynb If you’re curious about structured ML pipelines or modernizing legacy notebooks, this is a small but practical example of the process.  ( 6 min )

Introduction Hello everyone. My name is K.H. and I'm currently studying at a local university in Vancouver, Canada. Executing git push and automatic deployment (cd) I learned how to deploy a Django app to AWS EC2. I built a scalable configuration using Auto Scaling Groups and a Load Balancer. I used the stress command to apply CPU load and confirmed autoscaling operation. I learned basic configuration and monitoring methods for stable app operation in a cloud environment. I learned how to process form input with Django and dynamically generate results with Python. I was able to implement basic Python logic, including conditional branching, numerical calculations, and string manipulation. I understood the flow of data between Django views, templates, and forms.

If you come from MySQL, you might instinctively type SHOW TABLES; in PostgreSQL — and get an error. PostgreSQL doesn’t include that command, but there are easy alternatives. In this post, we’ll go through both ways to list tables: using psql’s built-in commands and SQL queries from the system catalogs. You’ll also see a few extra tricks to refine your results. Connect to a database from your terminal: \c postgres Then list all tables in the current schema: \dt Want to see all tables across schemas? \dt *.* You can also view details about a specific table: \d table_name Extra Tip: To display only tables owned by a user: \dt *.* | grep alice Use a query on PostgreSQL’s catalog or information_schema: SELECT table_name FROM information_schema.tables WHERE table_schema = 'public' AND tab…  ( 23 min )

🧩 Two Minor UI Glitches I Came Across on DEV Hey folks 👋 As a front-end developer (and a regular DEV community reader), I love exploring different sections of the platform — not just for the content, but also to see how beautifully Forem has built this space for developers. While browsing around recently, I noticed a couple of small UI inconsistencies that caught my eye. Nothing major, but I figured it’d be helpful to report them — both as part of the community and as someone who appreciates great UX. So, I opened GitHub issues on the Forem repository to share them with the team.

Understanding MCP Message Structure and Data Flow Hey there! If you've been diving into the Model Context Protocol (MCP) lately, you might have wondered how messages actually flow between clients and servers. I know I did when I first started exploring this fascinating protocol. Let me walk you through what I've learned about MCP's message structure and data flow in a way that (hopefully) makes sense. Before we jump into the nitty-gritty of messages, let's get on the same page. The Model Context Protocol is like a universal translator between AI applications and the services they need to interact with. Think of it as a standardized way for your AI assistant to talk to file systems, databases, APIs, or pretty much anything else. The beauty of MCP? It's built on JSON-RPC 2.0, which means i…  ( 10 min )

In any large organization, managing user identities is a constant challenge of balancing security with user convenience. For an enterprise-grade workflow orchestration platform like Apache DolphinScheduler, robust and flexible authentication is not just a feature-it's a necessity. Previously, DolphinScheduler offered several login options, including Password, LDAP, and Casdoor SSO. However, these methods had limitations, such as a high dependency on the Casdoor project or an inflexible OAuth implementation, making it challenging to integrate with diverse enterprise identity systems. As my Google Summer of Code 2025 project, I'm excited to introduce the solution: a that streamlines and modernizes access to DolphinScheduler, making it truly enterprise-ready.

One of the biggest obstacles for call centers to manage customer experience is noise. Agents working in hybrid or remote environments battle barking dogs, keyboard clicks, and street chatter that disrupts professionalism and clarity. The AI noise cancellation for call centers helps remove background noise, improving voice fluency, and ensuring every interaction sounds calm, confident, and human. Industry estimates suggest that poor audio quality can increase average handle time (AHT) by 15–20%, as agents and customers repeatedly ask for clarification. When calls become frustrating, customer satisfaction (CSAT) scores drop—and even skilled agents struggle to sound composed. For QA teams, reviewing noisy recordings wastes analysis time and lowers scoring accuracy. That’s why modern contact…  ( 9 min )

When you start learning backend development, it’s easy to focus on features, getting APIs to respond, connecting to the database, or just making it all work. In my projects built with FastAPI, I follow a simple but consistent pattern for error handling. For Example: from fastapi import APIRouter from sqlalchemy.exc import SQLAlchemyError from app.logger import logger # custom logger from app.database import get_db from app.models import Student router = APIRouter() @router.get("/students/{student_id}") def get_student(student_id: int): try: db = get_db() student = db.query(Student).filter(Student.id == student_id).first() if not student: logger.warning(f"No student found with ID {student_id}") return {"error": "Student not found"} logger.info(f"Fetched student: {student.name}") return {"student": student.name, "email": student.email} except SQLAlchemyError as e: logger.error(f"Database error while fetching student {student_id}: {e}") return {"error": "Database connection failed"} except Exception as e: logger.error(f"Unexpected error in get_student API: {e}") return {"error": "Something went wrong, please try again later"} Here’s what’s really happening behind the scenes: Every error is caught from database issues to unexpected runtime exceptions. Logs are categorized info for successful events, warnings for missing data, and errors for critical issues. No internal crash leaks to the user. Instead, users see a clean, friendly response while I get detailed error traces in my logs. The logger I use writes all messages to a local file, but also integrates with CloudWatch for live monitoring when deployed. It’s one of those invisible systems that keeps everything steady. Over time, I’ve learned that a stable backend isn’t the one that never fails it’s the one that knows how to fail gracefully and tell you exactly why.  ( 7 min )

Python bytearray Overview bytearray is an important built-in class in Python that represents a mutable sequence of bytes. bytearray is similar to bytes, but unlike bytes, bytearray is mutable. # Create a bytearray ba = bytearray(b'Hello') print(ba) # Output: bytearray(b'Hello') print(type(ba)) # Output: ba1 = bytearray(b'Hello') print(ba1) # bytearray(b'Hello') ba2 = bytearray('Hello', 'utf-8') print(ba2) # bytearray(b'Hello') ba3 = bytearray(5) print(ba3) # bytearray(b'\x00\x00\x00\x00\x00') ba4 = bytearray([65, 66, 67, 68]) # ASCII: A, B, C, D print(ba4) # bytearray(b'ABCD') # bytes is immutable (will cause error) b = b'Hello' # b[0] = 74 # TypeError: 'bytes' object does not support item assignment # bytearray is mutable ba = bytearray(b'Hello') ba[0] = 74 # ASCII code for 'J' print(ba) # bytearray(b'Jello') ba = bytearray(b'Hello') ba.append(33) # ASCII code for '!' print(ba) # bytearray(b'Hello!') ba = bytearray(b'Hello') ba.extend(b' World') print(ba) # bytearray(b'Hello World') ba = bytearray(b'Hello') # Convert to bytes bytes_obj = bytes(ba) print(bytes_obj) # b'Hello' # Convert to string string = ba.decode('utf-8') print(string) # 'Hello'  ( 6 min )

When I interview new developers or review resumes, I keep hearing the same question: Did I pick the right first programming language? Some candidates list four languages, trying to prove they’ve explored everything. Others feel they picked the wrong one—learning Python instead of Java somehow set them back.

I’ve seen engineers start with C, JavaScript, or Python and still grow into great developers. The difference wasn’t the syntax. It was the habit of building projects, finishing them, and learning from each one. Choosing a first language is career-defining because the tech world is noisy.

The first time I opened Xcode to build an iOS app, I thought I’d have something in the App Store within a week. I had the idea, the excitement, and a “Hello, World!” running on the simulator.

In modern application development, it’s rare to find a single-service system. Most real-world applications rely on multiple services working together — think of a web server, database, cache, and message broker forming one cohesive stack. Managing all these containers manually can be messy. That’s where Docker Compose becomes your secret weapon. Docker Compose is a simple yet powerful tool for defining and running multi-container Docker applications.

Create a PROMPT.md in your project root directory. Use it to store all the context necessary about your project for your agent to save yourself time from re-explaining what your project is or what your preferences and project level decisions are. Context is one of the hardest things currently when using LLMs. You're either telling the LLM what your project is in each chat, or the LLM gets lost in the sauce and forgets what it is your project is trying to accomplish, or how you're trying to accomplish it. Create a file in your project root that tells the LLM what it should know every time (you should even let the LLM write/update it also). There is a great talk by Elixir Phoenix create Chris McCord about how they are actively trying to make Elixir (and Phoenix) the best language to code with an LLM. They are mostly ensuring that it generates valid Elixir code like Enum.at(my_list, 0) instead of my_list[0] by defining Elixir syntax in a PROMPT.md file. He recommends to use that file as a base and expand on it. There's a good quote during the talk where Chris says something like: You can spend your time arguing about the morals of AI, or you can be 2-3 times more productive. You can be Michelangelo painting the Sistine Chapel, telling the assistants what broad strokes to make and do the stuff you don't want to do while you focus on the big picture and ensure the small details are right. Or you're a mangaka with assistants filling in cells, whatever. The skill of reviewing code and making sure your vision is followed becomes more important at all levels. Just because you are not hand typing every line of css, html, javascript, ruby, c++, whatever doesn't mean you aren't doing the thinking and solving the problems.  ( 6 min )

MERN Stack is a combination of four powerful technologies: MongoDB, Express, React, and Node.js. With these four tools, you can build modern, fast, and complex web applications. Let’s take a detailed look at the role of each component and what they can do together. 🗄️ MongoDB - Database: MongoDB is a NoSQL database that stores data in the form of documents. It works in a JSON-like format, which makes it very convenient to use JavaScript. You can store user lists, product catalogs, or any other type of data. Express.js is a minimalist web framework for Node.js. It simplifies server-side logic, such as routing and creating API endpoints. Express allows you to write a server quickly and in an organized manner. React is a library used for building user interfaces. It works on a component-based system, meaning you can create each part of your application separately and them combine them. This makes code reusable and easier to manage. Node.js allows you to run JavaScript code on the server. This enables the entire stack to use only one language - JavaScript - which simplifies the development process. 📱 Full-functional web applications 💼 Business applications (CRM, ERP systems) 🛒 Online stores (E-commerce) 📊 Data management systems (Dashboards) 💬 Real-time applications (Chat apps, notification systems) 🎮 Games and interactive applications With the MERN Stack, you can create powerful applications intended for the world using only JavaScript. By learning and applying this stack, you can significantly enhance your skills. 🔗 Connect: ibrohimbek.link  ( 6 min )

In my early days as a software engineer, I often wondered: how do teams migrate between databases without bringing everything down? It’s one of those invisible feats of engineering — moving millions of records, decomposing APIs, redefining schemas — all while users continue using the system like nothing happened. I recently had the opportunity to lead one of these migrations myself — a journey that pushed me to balance complexity and pragmatism, architecture and delivery speed, and “fancy” vs “effective” design decisions. It also pushed me to grow as an engineer, my team navigate a difficult impending blocker — navigating ambiguity, managing moving parts across systems, and learning to balance clean design with real-world delivery constraints. While there are famous war stories from brilli…  ( 10 min )

I’ve always found the intersection of audio and visual media fascinating. Ever wondered why some videos just stick with you, even when you can’t quite recall the content? I think a lot of it comes down to how well these two modalities are fused. Recently, I stumbled upon a piece of research that really caught my attention: Ovi, which stands for Twin Backbone Cross-Modal Fusion for Audio-Video Generation. Let me tell you, it’s a game-changer. When I first read about Ovi, I couldn’t help but feel that classic “aha moment.” This isn’t just another run-of-the-mill AI model—it’s an innovative approach that combines audio and video data in a way that’s both efficient and, frankly, mind-blowing. I’ve been exploring generative AI for a while, and while some models do a decent job at creating conte…  ( 9 min )

What Is Full-Stack Development? (A Simple Guide for Beginners) If you’ve ever heard someone say they’re a full-stack developer and wondered what that really means, you’re not alone. In simple terms, full-stack development refers to the ability to build both the front and back parts of a website or web application — everything users see and everything that runs behind the scenes. Think of it like building a house: the frontend is the design, furniture, and paint that people see, while the backend is the plumbing, wiring, and foundation that make everything work smoothly. 🖥️ Frontend: What Users See The frontend is the client side of a website — the part users interact with directly. It’s what you see when you open a web page: the layout, colors, buttons, forms, and animations. Frontend dev…  ( 7 min )

Reasoning Under a Cloud: Making Smarter AI Decisions with Fragmented Knowledge Imagine an AI trying to diagnose a patient with incomplete medical records. Or a self-driving car navigating a road where sensor data is intermittently lost. How can these systems make reliable decisions when the facts are fuzzy? The key lies in building AI that can not just process information, but also reason effectively with uncertainty. The core idea is creating a structured argumentation framework. Instead of treating arguments as black boxes, we analyze their internal structure—the premises and rules used to construct them. Then, we can model uncertainty directly within these components. This allows the system to weigh the strength of an argument based on the reliability of its foundation. Think of it li…  ( 7 min )

When it comes to software development, quality can make or break a product. But one persistent myth keeps popping up: Quality Assurance is just another word for testing. It’s easy to see why, testing is the most visible part of the process, but QA is so much more. Think of it as the entire system of practices that keeps quality top of mind from start to finish. Yes, testing is part of it, but QA includes planning, design reviews, coding standards, documentation and continuous improvements that prevent problems from ever reaching users. It’s about building quality in, not just checking for bugs at the end. For decision makers, understanding this bigger picture is key. Seeing QA as a strategic end to end approach rather than a single task is what separates average software from products that…  ( 12 min )

The emergence of advanced AI models has made it necessary to create standardized techniques for supplying them with real-time, external, or domain-specific data. A technical specification known as the Model Context Protocol (MCP) outlines the client-server communication necessary to provide this context. An MCP server, an application in charge of exposing specialized data sources like issues from Linear, design files from Figma, or repository code from GitHub, communicates with an MCP client (such as Gemini or GitHub Copilot). The LLM can perform tasks and reasoning that would be impossible with its base knowledge alone thanks to this client-server model. This fundamental feature of providing context to models was initially put forth in architectures such as Anthropic's Ask to Ask (A2A…  ( 10 min )

Modern displays are more than just LCD panels and touch sensors. Between the layers that make up your smartphone, automotive dashboard, or industrial HMI, there’s a transparent film doing critical work — the Optical Clear Adhesive (OCA). This adhesive is the reason screens stay bright, responsive, and durable even in challenging conditions. In this article, we’ll explore what OCA is, why it’s used, and how it’s changing display manufacturing. OCA is a transparent adhesive film used to bond optical layers together — such as the cover glass, touch panel, and display module. Unlike liquid adhesives, OCA comes as a pre-cast solid sheet. During assembly, it’s applied under pressure and temperature to create a bubble-free optical interface between components. In simple terms: OCA replaces th…  ( 8 min )

Introduction. The Beating Heart of Intelligent, Autonomous AI Agents If you’ve ever written a for or while loop in programming, you already understand the core idea behind the Agent Loop. It’s a cycle a repeating process that continues until a condition is met. But when it comes to AI agents, this loop becomes much more powerful. It’s not just about iteration; it’s about reasoning, tool use, and autonomous decision-making. In the AWS Strands Agentic Framework, the Agent Loop is the engine that powers intelligent behavior. It continuously processes input, reasons through possible actions, calls tools, and generates responses all while maintaining context and adapting to new information. This post dives deep into how this loop works, its key components, and why it’s at the heart of model…  ( 9 min )

Introduction Random testing can explore broad state spaces but often leaves gaps. Directed tests provide structure but risk missing unexpected interactions. The most effective approach combines the two: constrained-random stimulus for breadth and directed suites for precision [2]. The Challenge: Random Alone Is Not Enough Directed suites can systematically validate those features, but cannot anticipate subtle corner cases. Together, these limitations highlight the need for a combined strategy. Random stimulus is used to discover the unexpected, while directed suites guarantee compliance with the specification [3]. Note that compliance is a necessary but not sufficient measure for verification. Constrained-Random Testing with STING Constrained-random test generation is often the starting po…  ( 11 min )

In the previous article, we introduced a PostgreSQL database to our forum, achieving persistent data storage, so that data is no longer lost even if the server restarts. Now we can confidently make more improvements. However, you may have noticed that all of our current interface styles (HTML) are written directly in main.py. Does this mean that for every new feature in the future, we have to stuff more HTML into main.py? This is not only troublesome to write, but it also leads to a large number of HTML strings being mixed into the Python code, making the code difficult to read and maintain. To solve this problem, this article will introduce the Jinja2 template engine to separate the backend logic (Python) from the frontend presentation (HTML), making the project structure clearer and easi…  ( 9 min )

If you've heard the folk tale of John Henry, you know the story: a steel-driving man who raced against a steam-powered hammer to prove human worth and dignity. He won the race but died with his hammer in his hand. It's a powerful allegory about technological change, human pride, and the cost of resistance. Today, as AI coding assistants become ubiquitous in software development, many developers feel like they're staring down their own steam-powered hammer. The anxiety is real—will AI replace us? Should we resist? Are we racing toward obsolescence? But here's what the John Henry story often obscures: the steam engine didn't eliminate workers; it transformed work itself. The railroad industry exploded after mechanization. More tunnels were built, more tracks laid, more infrastructure created…  ( 16 min )

There is a quiet moment, just after a feature is "done," when you click a link and witness the browser's brutal ritual. The entire page—the meticulously crafted header, the complex sidebar, the persistent player—blinks out of existence. For a heart-stopping second, there is nothing. Then, it all rushes back, reassembling itself just to update a small counter in the corner. We've accepted this as the cost of doing business on the web. Our server renders a complete, holistic page, a single, indivisible block of HTML. But our users don't experience the page as a monolith. They experience it as a collection of independent components: a shopping cart, a live feed, a search result list. What if our technology reflected that reality? What if, instead of sculpting from marble—a single, heavy block…  ( 10 min )

liner notes: Professional : Today started off rough, but got better through the day. Totally forgot about a meeting because the company logged me out of Slack on my phone and I'm not able to log into my work calendar, so I got no notifications and was locked into coding. Speaking of coding, I got a demo started but ran into a road block. The good news, I think I know a way to get around it. Personal : Did a bunch of sketching and design for some stickers. I did some measurements and modified a model. I also went through some projects on Bandcamp that I plan to pick up this week. I thought of another prototype that I want to make to show the prospective client. Been thinking and researching the best way to be able to print it reliably. I'm thinking I may go back and put in a little bit of time in the demo I was building for work. I think a couple of hours tonight will save me a bunch of time tomorrow because I won't have meetings or people asking me questions and I'll be able to focus. Like I said, I think I have an idea of what I need to do to be able to get it to a good place to be able to demonstrate the idea. Yeah, I'll work on that and get back to putting together the social media posts for the Bandcamp projects and think and sketch more the prototype and stickers. It's getting dark, going to eat dinner and get to work. Have a great night! peace piece https://dwane.io / https://HIPHOPandCODE.com  ( 6 min )

There’s a moment in every seasoned Rails developer’s journey when the app/models directory stops feeling like a well-organized toolbox and starts to resemble a junk drawer. You know the one. It’s where the User model, a proud and complex entity, lives next to a ReportGenerator concern, a PaymentService class, and a NotificationsHelper that’s seen things. We started with a beautiful, coherent BlogPost model. Then came FeaturedBlogPost. Then SponsoredBlogPost. Then the BlogPost::ExportToNewsletter service object. Our once-simple domain has become a tangled web. We’ve been building a Monolith, and without a map, we’re getting lost in our own city. It’s time to become cartographers.

You’ve just been assigned to The Monolith. It’s not a pejorative; it’s a title earned through years of service. This Node.js codebase is the bedrock of your company—a sprawling, complex entity with layers of history etched into its very structure. You git clone, run npm install, and are greeted not by errors, but by a different kind of challenge: the weight of legacy. In the heart of this digital forest, you find trails overgrown with tangled functions, campsites littered with // TODO comments, and ancient, runic code that everyone is afraid to touch. The pressure is always to build the new feature, to hack in the hotfix. But you know that unmanaged entropy is a technical death sentence. This is where we embrace a different philosophy.

Building Streaky: A GitHub Streak Guardian Part 1: The Journey from "Simple App" to Distributed System I thought building a GitHub streak reminder would take a weekend. It took 3 weeks and taught me more about distributed systems than any tutorial. The "simple" idea: Check users' GitHub contributions daily Send Discord/Telegram notification if they haven't committed That's it What actually happened: 5 failed attempts, CPU limits, IP blocking, race conditions, and a complete architecture redesign. I kept losing my GitHub streak because I'd forget to commit on busy days. Existing solutions were either: Self-hosted (requires always-on server) Paid services Missing Discord/Telegram integration So I decided to build my own. How hard could it be?

I saw the original Isotope Javascript fancyness and I just had to write a rebuild using modern web standards. Check out my rebuild! My version of Isotope uses a grid layout and animates using view transition. It is silky smooth, blazing fast and has graceful degredation. The code consists of only 63 lines of vanilla JS, while the old version required an astonishing 3500+ lines. If you choose to leave the sorting out, you can even reduce the code to 37 lines. Yup... the web has come a long way. Just set id="isotope" on any container and give its children classes that represent categories, like class="metal". Then create some buttons with data attributes, like data-filter=".metal" or data-sortby="symbol". Load the JS from the demo in the footer and it works. You don't need ANY of the CSS. That is all just fancy stuff. Note that my version only supports basic filtering and sorting (which are the only things I ever used from the original code). Also note that the animations do not work in Firefox (yet). Finally, be aware that you can not use this Isotope filter twice on the same page, as it lacks abstraction for that.  ( 6 min )

You stand before the loom of your application, a Senior Developer, a master of the craft. You've honed your Node.js to a fine edge. Your REST APIs are elegant, your service logic is pristine, and your unit tests are a suite of gleaming, isolated sculptures. They are beautiful, but they are individual pieces. They don't tell you if the tapestry, when woven together, will hold. The database layer is that tapestry. It's the interconnected weave of data, relationships, and state that can make or break your application. Unit tests mock the database, admiring the loom from a distance.

⚠️ Warning: The "Overfitting to a Single Data Point" Pitfall In AI-powered media analysis, it's easy to fall into the trap of overemphasizing a single data point that may not be representative of the larger trend or dataset. This phenomenon is known as "overfitting to a single data point." It occurs when a model is heavily influenced by an outlier or an unusual observation, leading to inaccurate conclusions and flawed insights. For instance, consider a media analysis project where a model is trained to predict the sentiment of social media posts about a particular brand. If the dataset contains a single post with an extremely positive sentiment, the model may learn to associate the brand with an overly optimistic tone. However, this might not reflect the actual sentiment of the majority of the users, potentially leading to a biased perception of the brand's reputation. To avoid this pitfall, data scientists and media analysts must employ robust methods to validate their findings.... This post was originally shared as an AI/ML insight.

If you’ve been working with APIs for a while, you’ve probably bumped into Postman. Maybe you even used it once or twice and thought, “Okay, nice little GUI for cURL.” That’s what most people think at first. I did too. But here’s the truth: Postman isn’t just a fancy interface to send GET or POST requests. It’s an entire development environment built around how real teams actually design, test, and debug APIs. Once you understand what it can do, it’s hard to imagine building or maintaining APIs without it. Let’s go step by step—through what I like to call the “levels” of Postman use.

Binary Hardening in Rust (and Beyond) Hello stranger of the internet, and welcome back! Rust developers have access to powerful binary hardening techniques that make reverse engineering significantly harder—from compile-time string encryption and control flow obfuscation to self-integrity checks and memory protection. These aren't theoretical concepts: they're practical strategies that raise the cost of tampering and credential extraction in production software. Binary protection isn't just paranoia, or maybe is... Every application that ships to untrusted environments—whether compiled binaries, bytecode, or bundled JavaScript—needs defenses against tampering, credential extraction, and reverse engineering.

Article Short Review Meta‑Awareness Enhancement in Large Language Models The article investigates the meta‑awareness of reasoning models—how language systems internally gauge their own problem‑solving processes. By demonstrating a pronounced misalignment between predicted meta‑information and actual rollouts, the authors argue that current large language models lack true self‑knowledge. To address this gap, they introduce Meta‑Awareness via Self‑Alignment (MASA), a training pipeline that leverages self‑generated signals rather than external datasets. MASA incorporates two efficiency strategies: filtering out zero‑variance prompts and truncating unlikely rollouts, thereby reducing computational overhead. Experimental results show significant accuracy improvements across in‑doma…  ( 8 min )

For a long time, “protein” was almost synonymous with chicken, eggs, and whey shakes. But today, more people are realizing that you can build muscle, stay energetic, and maintain great health entirely on vegetarian or plant-based foods — as long as you know where to get your protein and how to balance it. Whether you’re vegetarian for health, environmental, or ethical reasons, this guide will show you how to meet your protein needs naturally. Why Protein Matters Protein isn’t just for bodybuilders. It’s the foundation of every cell in your body — from muscles and bones to skin, enzymes, and hormones. It repairs tissues, supports immunity, and fuels metabolism.

You publish an article. It gets some views. Maybe a few reactions. But then what? DEV.to's built-in analytics show you the basics, but they don't answer the questions that actually matter: Which tags are driving the most traffic? Is my content getting better over time? Which old articles should I update? What's my actual engagement rate? Should I be using different tags? After publishing 16 articles and hitting 983 views, I realized I was flying blind. So I built DEV.to Analytics Pro - and the insights completely changed my content strategy.

Nowadays, when a user visits our website or web application using a mobile, tablet, or laptop — he should be able to use it comfortably. This is the main purpose of responsive web design. Responsive design means the layout, text, images, buttons, etc. will adjust automatically according to the screen size. 1. Mobile-First Approach We have to start our design with small screens like mobile. Then, gradually, we can expand the design for larger screens. 2. Viewport Meta Tag Usage In the tag of HTML, the viewport meta tag is required. The code looks like this: It helps the website become responsive according to the device’s viewport. 3. Using Max-Width for Layout Control and Center Alignment On large screens, the website content should not be too wide horizontally, and on small screens, it should fit properly and look good. .container { max-width: 1200px; margin: 0 auto; padding: 0 20px; } Every modern website uses this technique. 4. Relative Units and Flexible Layout We should use %, rem, or em instead of pixels. .container { width: 90%; } 5. Using Flexbox and Grid Layout In the past, people used float-based layouts, but nowadays, the simplest and most modern solution is using Flexbox and Grid. 6. Making Images and Videos Fluid We have to use relative units and avoid fixed pixel sizes for images. img { max-width: 100%; height: auto; } 7. Responsive Typography If the screen is small, font sizes should also be smaller; otherwise, they will look oversized. 8. Responsive Navigation Menu The navigation bar is one of the most important parts of a website. We can use media queries for small screens and convert the menu layout into a vertical one. Responsive web design is now a mandatory part of modern web development. If we can properly use HTML, CSS, Flexbox, Grid, and Media Queries, we can build websites that work smoothly and beautifully across all screen sizes.  ( 8 min )

🧩 1. Understanding What a “Database Connection” Is A Database Connection is a communication channel between your Java application and a database (e.g., MySQL, PostgreSQL, Oracle, etc.). It uses JDBC (Java Database Connectivity) under the hood. A connection is required to: Execute queries Fetch / insert / update data Commit or rollback transactions Level 1 — Raw JDBC Connection (Manual Way) This is the most basic way: DriverManager. Each time a request comes, app opens a new connection. No pooling or optimization.

🧩 1. What is a Constructor? A constructor in Java is a special method used to initialize objects. no return type. Example: public class Person { private String name; // Constructor public Person(String name) { this.name = name; } } Constructors are called when you create an object: Person person = new Person("Gaurav"); A default constructor is a no-argument constructor that Java automatically adds if you do not define any constructor in your class. Example: public class Employee { private int id; private String name; } The Java compiler automatically adds: public Employee() { super(); // calls Object class constructor } So you can still do: Employee e = new Employee(); // ✅ Works fine If you explicitly define any constructor (parameterized or no…  ( 9 min )

I built a minimal Spring Boot service for my HNG Stage‑0 backend task that returns a profile object plus a fun cat fact. The goal was to deliver a clear, runnable microservice in a few files so reviewers can quickly run and inspect the code. What it does Exposes GET /me Returns a JSON payload with status, a small user profile (name, role, links), a timestamp, and a cat fact fetched from https://catfact.ninja/fact Architecture (short) ProfileController — handles /me and returns a ProfileResponse DTO. ProfileService — builds the profile and fetches the external cat fact using Java HttpClient. Profile (domain) and ProfileResponse (DTO) — simple POJOs for shape and serialization. Spring Boot entrypoint and a single minimal unit test to ensure application context loads. Why this shape? Minimal surface area: reviewers can audit the domain, controller, and service quickly. External call isolated in the service so it’s easy to mock or replace. Small codebase is ideal for early-stage tasks and focused feedback. How to run locally From the project root (uses the included Maven wrapper): ./mvnw spring-boot:run Then open: http://localhost:8080/me What I learned / next steps Keep services focused and small for fast review cycles. Inject HttpClient (or a wrapper) to make the external API call testable and mockable. Add structured error handling and logging for robustness. Add unit tests that mock the cat-fact API and an integration test for the controller. check the repository: here  ( 6 min )

On October 20, 2025, one of AWS’s largest data centers in Virginia went dark. A DNS failure during a DynamoDB API update cascaded into a massive global outage, crippling over a thousand services - from banking apps to crypto networks like Coinbase, Base, and Infura. It was another reminder that almost everything online, even “decentralized apps,” still runs on someone else’s computer.​ AWS had become the beating heart of global infrastructure. So, when it stumbled, the internet staggered. But what truly caught the crypto industry’s attention wasn’t that Coinbase or OpenAI went dark - it was that Ethereum access through Infura also went down.​ That led to an uncomfortable question: if blockchain is supposed to be decentralized, why does a bug in one AWS region bring half of Web3 to its knee…  ( 9 min )

Learnings from the recent AWS failure. It started with confusion. At 7:40 AM BST on October 20, 2025, a Monday morning like any other, people around the world reached for their phones and found... nothing. Duolingo wouldn't load—goodbye, 500-day streak. Snapchat refused to open. Ring doorbells went blind. Wordle players stared at blank screens, their morning ritual interrupted. Coinbase users couldn't check their crypto portfolios. Even Amazon's own shopping site was struggling. On Twitter (somehow still working), the complaints began flooding in. "Is it just me or is everything down?" Thousands asked the same question simultaneously. Within minutes, Downdetector lit up like a Christmas tree—over 50,000 reports cascaded across services that seemingly had nothing in common.

Hi everyone, I'm facing a lot of issues — there are many models, many open-source ones, and many others that are quite costly — but none can guarantee that 100% (or even close) of the data will be extracted correctly from my PDFs, DOCX files, or other formats. I also have another problem: I'm Italian and want to build this for an Italian audience, so the documents will be in Italian — and some extractors don’t handle that very well. So my question is: what kinds of systems, tools, or approaches do you use to extract all the information from your documents before the chunking and embedding phase? Let me know, thanks!  ( 6 min )

I get that desktop applications are out of style these days. But they are still a good way to deliver powerful features and high performance graphics. However, delivering modular Java applications on Windows is a challenge. It almost seems like Java and Windows have conspired against each other. Java requires that all module jars are listed in one command line parameter. That works fine when Unix shells have a >100K character command line. Windows batch files have a relatively short limit (8191) on the lengths of their command lines. This makes it impossible to launch large-ish modular Java applications on Windows using the standard scripting model of every parameter on the JVM’s launch command line. The work around is to specify an argument file (e.g. @app.args) when launching Java.…  ( 10 min )

Pods on the affected node cannot communicate with pods on other nodes. The node's status is "not ready" in the Kubernetes cluster.

I’ve been doing the job hunt all wrong. Like many of you, I’ve been on the hunt for a few months now and it can be exhausting. Sending application after application and hearing nothing back is demoralizing. A few weeks ago, I attended the Commit Your Code tech conference in Frisco, TX, and it truly changed everything for me. I met an incredible community of developers helping each other learn, grow, and navigate today’s job market, especially through the 100Devs and CYC Discords. I’ve been in the industry for over six years, but the most important thing I’ve learned recently wasn’t technical — it was personal. Back in 2021, when dev demand was at an all time high, I was spoiled. I didn’t have to apply for jobs. A friend made an intro, I interviewed, and BOOM, hired immediately. For better or worse, that market’s gone now, and for a while, I was still acting like it wasn’t. I’ve had to accept that I can’t take employability for granted anymore. The game has changed. I need to be proactive in new ways: by networking intentionally, building real connections, and creating a visible online presence. This shift hasn’t exactly been intuitive for me. Funny enough, we’re expected to pivot constantly on the job, by learning new stacks and new systems; when it comes to our own careers, that same adaptability can be hard to find. But here’s the thing: problem-solving is what we do. So if you’re out there grinding, wondering if it’s still possible, know that I think it is. Rethink your strategy. Build proof. Connect with people who are learning and sharing too. It’s not easy work, but it beats sending 1,000 applications into the void. You’ve got this. 👊  ( 7 min )

It is well known that software development is a lifelong learning process. At the start of my career, most of my early interactions involved SQL databases. I used many SQL administrative tools, such as DBeaver, SQLiteStudio, and MySQL Workbench. When I first began working with DynamoDB, I didn’t realise early enough that I needed a mindset shift, and I am sure quite a few developers fell into a similar trap. In designing my DynamoDB table structure, I treated queries and access patterns as afterthoughts and focused more on mappings and relationships between items and entities, just as I would with a relational database. Persistently applying these old SQL habits often led me to deal with inefficient scans, which was deeply frustrating. When working with DynamoDB, you need to shift your min…  ( 9 min )

Changing Password Supabase provides a built-in functionality for resetting passwords via a link. However, if you want to change your password while logged in, there is no built-in functionality for this scenario. To handle this, you can use a custom function on Supabase. Run the following code in your Supabase SQL Editor: create or replace function changepassword("current_plain_password" text, "new_plain_password" text, "current_id" uuid) returns varchar language plpgsql security definer as $$ DECLARE encpass auth.users.encrypted_password%type; BEGIN SELECT encrypted_password FROM auth.users INTO encpass WHERE id = current_id and encrypted_password = crypt(current_plain_password, auth.users.encrypted_password); -- Check the currect password and update IF NOT FOUND THEN return 'incorrect'; else UPDATE auth.users SET encrypted_password = crypt(new_plain_password, gen_salt('bf')) WHERE id = current_id; return 'success'; END IF; END; $$ This will create a custom function that you can call from any platform. Here’s the syntax for Javascript: const { data, error } = await supabase.rpc('changepassword', { current_plain_password: oldPassword, new_plain_password: newPassword, current_id: currentUserId }); Here- current_plain_password is the old password new_plain_password is the new password current_id is the id in the current session of the app. Logging Out from Active Sessions on Other Browsers/Devices To sign out from all active sessions, you can use the following commands: // defaults to the global scope await supabase.auth.signOut() // sign out from the current session only await supabase.auth.signOut({ scope: 'local' }) // sign out from the other session without the current await supabase.auth.signOut({ scope: 'others' }) Upon sign out, all refresh tokens and potentially other database objects related to the affected sessions are destroyed and the client library removes the session stored in the local storage medium.  ( 7 min )

When working with React Router v6, I found myself wishing for a feature that doesn’t exist — parallel routes. That’s why I built parallel-router 💡 The Problem React Router v6 is amazing, but it doesn’t natively support rendering two distinct route outlets at once. ⚙️ The Solution parallel-router introduces a wrapper that allows multiple route contexts to exist side by side: This makes it super easy to create layouts like: Chat apps (list + conversation) Dashboards (menu + content) Multi-view editors 📦 Try it out: 🔗 NPM: https://www.npmjs.com/package/parallel-router 🔗 Docs & Demo: https://salekin02.github.io/parallel-router 🔗 GitHub: https://github.com/salekin02/parallel-router 🧠 What’s next I’m planning to extend support for other versions of React Router and would love your feedback on what features you’d like to see next!

DevOps is more than a role; it's a culture and mindset that bridges the gap between development and operations. Any member of an IT organization or software company can embrace DevOps principles to improve collaboration, streamline processes, and enhance software delivery. Any person can carry more than one role. However, the literature for DevOps often starts with operations: system administrators, infrastructure engineers, and site reliability engineers (SREs). One of the best books on the topic, The Phoenix Project, is written from the perspective of an operations manager (and I highly recommend reading it). DevOps is about operations, but it is also about development. In truth, DevOps is about the entire software lifecycle and thus any person involved in it can learn and grow into a De…  ( 12 min )

Escolher entre uma arquitetura monolítica e uma arquitetura de microsserviços é uma das decisões mais importantes no desenvolvimento de software. Cada abordagem possui pontos fortes, fraquezas e casos de uso ideais. A escolha certa depende do tamanho do seu projeto, do estágio de crescimento e dos requisitos técnicos. Quando Usar um Monólito Monólitos são frequentemente usados por startups e equipes pequenas, pois são simples de iniciar. No entanto, à medida que a empresa cresce, geralmente é recomendado migrar para microsserviços para alcançar maior escalabilidade. Dito isso, não existe uma regra absoluta: cada projeto tem suas próprias necessidades, e a arquitetura deve se adaptar a elas.

Hi everyone! 👋 I’m the developer behind a little project called PleaseRSVP.ai — a simple tool that helps parents create beautiful AI-generated birthday invitations in under a minute. 🎂✨ The idea came from my own struggle as a parent — every year, I’d spend hours trying to design a nice invite for my kid’s party. Between juggling work and family, I wanted something that looked great but didn’t take forever to make. So… I built it! You enter your child’s name, age, date, and location — and the system instantly creates a themed invitation with a built-in RSVP page. Right now, new users can generate one invitation for free — no signup hassles, no limits. If you have a few minutes to try it, I’d really love your honest feedback or suggestions! ❤️ Thanks so much! — Ned  ( 6 min )

I have wanted to write about tech conferences for a while, and last week I was at Codemotion in Milan. Perfect excuse to finally do it. If you follow me here you know I usually share tutorials and technical content, but there is another huge part of our craft that I discovered only a few years ago: conferences. They open new opportunities and new ways of thinking that you will miss if you only focus on the tech. That would be a shame. While I am still wearing the conference badge, here is why I think you should go to large tech events, what to expect, the pros, and yes, the cons.

Recently, our People & Culture team shared something in our Learning Nuggets Slack channel: “The Four Tendencies” quiz, a framework by Gretchen Rubin that explores how people respond to expectations. The premise is straightforward: we all face external expectations (from others) and internal expectations (from ourselves). The way we respond to these defines which of the four tendencies we belong to: “I do what others expect of me—and what I expect from myself.” They meet both outer and inner expectations with discipline and consistency. Their motto: “Discipline is my freedom.” “I do what I have to do. I don’t want to let others down, but I may let myself down.” They readily meet outer expectations but struggle with self-imposed ones. “I do what I think is best, according to my judgment.

We gave an AI Coding Assistant a design file. Here is what happened. AI is changing everything - including how we build software. Coding assistants are everywhere, and the hype is real. But so are the concerns: Will it scale? Can I trust the output? What happens when things go wrong? We get it. We are a software company ourselves and like everyone else: we are under pressure to deliver more, faster and smarter. So we asked us a simple question: what if we could make AI coding assistants "safe by design"? In our product, architecture and design are not an afterthoughts. They are executable assets packaged as living design files that define: what gets built, how it works and why it matters. So we took a coding assistant - in this case, the choice fell on Cursor - to run a hackathon. We didn’t write user stories. We didn’t hand over vague requirements. Instead, we fed the coding assistant the structured design artifacts generated from the knowis Workbench. Simple. The Result? It worked well: Code generation was fast, focused, and aligned with our intent. Architecture guardrails stayed intact, even with rapid iterations. Review and testing? Easier than ever. Shifting the (investment) focus to the "left" of the software development process doesn’t just mean testing earlier. It means thinking, designing earlier. Better. Because AI accelerates code but architecture and design defines what gets built. In a few words: you don’t need to fear coding assistants. You need to feed them better inputs.

My two kids are quite different. The younger one is our chatterbox while the older one barely shares a thing. "How was school? Fine." At 'circle time' in school, every kid is supposed to go around sharing one thing that makes their heart happy. My kid has 'passed' every.single.time. for over a year! Needless to say, this has been a delicate balance in our household of trying to get more but not be pushy about it so we create a safe space. Well, we had a breakthrough over the weekend! We hosted friends for a few nights and got to witness one of their family rituals - "highs and lows". Every night, this family shares one high and one low they experienced during the day. Usually done over dinner but if they can't all be present, right before bed time. I think one of the keys is that everyone is involved. Level the playing field. They invited us to do it with them one night and I was sure my kid would pass as she scrambled to hide behind my partner and look away from everyone waiting for a response. To my utter shock, she participated! Enthusiastically. My partner and I were shocked, and decided this was something we would need to try again. And we have, and it's worked! She will thoughtfully reflect on her day and pull out something that made her happy, and something she was less than pleased about. It's not a super long conversation but it feels special that it's coming honestly from her as opposed to a response to some sort of interrogation by us. I'm hoping this can be a new daily routine...forever? If we can bake it in as just how our family functions, I hope we can hold it through the teenage years and beyond. Anyway, just wanted to share! I know there are a million tricks out there so this is just one of many you could try if you have a quiet kid too.  ( 8 min )

Εισαγωγή — Τι είναι το JWT (JSON Web Token) Το JWT (JSON Web Token) είναι ένα compact, URL-safe φορμάτ για να μεταφέρεις αξιώσεις (claims) ανάμεσα σε κόμβους (client ⇄ server). Ένα τυπικό JWT αποτελείται από τρία μέρη, χωρισμένα με τελείες: Ένα JWT έχει αυτή τη μορφή: xxxxx.yyyyy.zzzzz xxxxx → Header (π.χ. τύπος + αλγόριθμος υπογραφής) yyyyy → Payload (τα claims) zzzzz → Signature (η ψηφιακή υπογραφή) 1. Header — περιγράφει τον αλγόριθμο υπογραφής και το τύπο, π.χ. { "alg": "HS256", "typ": "JWT" }. 2. Payload — JSON με claims (π.χ. sub, exp, iat, roles, custom claims). Αυτό το κομμάτι — το “Payload” μέσα στο JWT — είναι ουσιαστικά η καρδιά του token, εκεί που αποθηκεύονται οι πληροφορίες (claims) για τον χρήστη ή τη συνεδρία.

Sí, he encontrado el lenguaje de programación perfecto. Ni C# ni Python, que son los que he estado empleando hasta este momento, son capaces de cubrir mis necesidades como puede hacerlo GulfOfMexico. Merece la pena echarle un vistazo. ¿Booleanos true/false? Eso es demasiado limitante. Los booleanos pueden tener tres valores: true, false y maybe. Hay verdaderas constantes. ¡Solo márcalas insistentemente con const! Por cierto, sí, el final de instrucción es la exclamación ('!'). const const const pi = 3.14! ¿Listas que empiezan en 0 (como C), o en 1 (como en Basic)? ¡Mejor en -1! Por cierto... ¡Por fin! ...puedes acceder a posiciones con números reales, en coma flotante. const var scores = [3, 2, 5]! scores[0.5] = 4! // 3, 2, 4, 5 Los operadores past y previous permiten consultar el pasado... y el futuro. const var score = 5! score++! print(score)! //6 print(previous score)! //5 print(next score)! //7 ¿Tu código solo fluye de arriba a abajo? ¡Estás obsoleto! Déjame presentarte la instrucción reverse. Buena parte de esta flexibilidad es la posibilidad de sobrecargar variables. const const message = "Hello"! print(message)! const const message = "world"! reverse! Además, hay que tener en cuenta que la palabra clave function cuenta con todos los alias resultantes de eliminar letras (en orden) de esta palabra clave: fi bonacci (n) => { const var sum = 1! const var i = 0! when (i < n) { sum += sum + previous sum! i++! } } Por no mencionar el operador delete, que permite eliminar aquellos elementos que nos estorben. delete null! // El error del millón de dólares delete 13! print(12 + 1)! // Error! ¿A qué esperas? ¡Adelante, instálalo y disfrútalo! Eso sí, ten en cuenta que es necesario instalarlo a través de su instalador. A su vez, el instalador debe instalarse mediante el instalador del instalador.  ( 7 min )

LLMs as Data Mines: Unearthing Gold from 'Thought' Circuits Ever felt like you're drowning in data, but still struggling to find the right examples to train your AI? You're not alone. Feeding your large language model (LLM) the perfect diet is key to unlocking its full potential, but sifting through mountains of information is a real bottleneck. What if the LLM itself held the secret to curating that ideal dataset? The core idea is simple: LLMs, when tackling complex tasks like math problems, activate specific, interconnected groups of 'neurons' – think of them as dedicated 'thinking' circuits. We can measure how strongly different data points activate these critical circuits within the LLM. The data that lights up these circuits the most intensely is, unsurprisingly, the most relevant a…  ( 7 min )

AI agents are becoming more powerful every day. They can chat, write code, answer questions, and help with tasks that once required human reasoning. They all share one challenge: how to handle knowledge/context over time. Two architectural patterns have emerged to fill this gap: Retrieval-Augmented Generation (RAG) and Memory. Both aim to make large language models (LLMs) more capable, context-aware, and cost-efficient. Yet they solve different problems and fit different stages of an agent’s lifecycle. In this article, we’ll explore both in simple terms, show how they differ, and explain when to use each, or both together. LLMs are stateless by design. Each prompt is processed independently; once you send a new request, the model forgets everything that happened before unless you include i…  ( 10 min )

How document-driven structure transforms stateless AI assistance into continuous, auditable engineering You're in your fifth AI session today. The code is flowing faster than you've ever experienced. Then you ask the AI to integrate yesterday's work—and it has no idea what you're talking about. This is the paradox of modern AI-assisted development: your code appears faster than ever, but your project feels more fragile. Research from GitHub, IBM, and METR documents what developers are experiencing: AI excels at generation but struggles with integration. In isolated sessions, output is fast and often high-quality. Across multiple sessions, coherence breaks down. Context vanishes. An AI might write a perfect authentication handler today, then suggest changes tomorrow that silently break it. …  ( 17 min )

Summary Lede : Enterprise systems often operate in silos, forcing users to switch contexts and applications to complete business tasks. By connecting SAP’s robust business processes with Microsoft Copilot Studio agents, organizations can now bring critical operational data and transactions directly into Microsoft 365 and Teams—where people already collaborate. This integration enables AI-driven, conversational interactions with SAP systems, eliminating the need to switch applications and accelerating decision-making and productivity across the enterprise. Bringing SAP data and actions directly into Copilot Studio agents puts your operational truth in the same place people already collaborate — Microsoft 365 and Teams — so users don’t have to switch tools or context when they need to look u…  ( 8 min )

I recently spent 3 hours debugging a simple config file parser. What should have been a 5-minute task turned into a nightmare of BufferedReader, try-with-resources, charset issues, error handling, and manual backup management. I realized Java's file I/O is scattered and outdated. That's why I built OpenLoom, a modern, zero-dependency Java library that unifies reading, writing, searching, and managing files efficiently. Traditional Java file I/O often looks like this: try (BufferedReader br = new BufferedReader(new FileReader(file))) { String line; while ((line = br.readLine()) != null) { if (line.contains("config=")) { // Logic buried in 20+ lines } } } catch (IOException e) { // More boilerplate } Search/Replace requires manual loops and backup…  ( 7 min )

If you’ve ever tried to move from one major version to another, you know it’s not just about running bundle update rails and calling it a day. Things break, dependencies complain, tests start failing, and suddenly what was supposed to be a “simple upgrade” becomes a sprint-long debugging marathon. That’s where being prepared can make or break your release. At RailsFactory, after helping dozens of teams navigate Rails upgrades (some smooth, some not so smooth), we realized something simple: most upgrade headaches start way before the upgrade actually begins. So, we created something to help you avoid all that mess, a Free Rails Pre-Upgrade Checklist. It’s not just a list of things to tick off. It’s a safety net for your next release. A Rails upgrade touches everything - from your app’s dep…  ( 8 min )

C# 14 is almost here, so it's time for our annual feature overview. This year brought fewer changes than the last. Some might consider them minor, but is it really so? Let's take a closer look. Yes, we can now omit writing a field for a property. Some might say that we could already write properties like this: public string Name { get; set; } This is an auto-implemented property, which creates a hidden field. However, the problem is that it can only be used when no additional logic is required. If we need such logic, we have to create a field just to store the data so we could process it in the property setter. For example, when we need to trim whitespaces from an email address before saving it, we would typically write something like this: public class User { private string _oldEmail;…  ( 12 min )

In today’s fast-paced digital world, automation isn’t a luxury — it’s a necessity.

GitHub Home It was another Black Friday. At 3 AM, my phone started screaming like crazy. 😱 It wasn't my alarm; it was the monitoring alert. Our flagship e-commerce service, the system we had poured six months of hard work into, had crumbled like a paper house in the face of peak traffic. CPU at 100%, memory overflows, and logs filled with timeout errors. 💸 That night, we lost millions in sales and, more importantly, our users' trust. It was one of the darkest nights of my career. 🔥 From that day on, I understood a principle: performance is not an option; it is the lifeline of a service. As an old-timer who has been in the coding world for nearly forty years, I've seen too many teams make mistakes when it comes to performance. They are either too optimistic, believing that "hardware will…  ( 10 min )

Hey #Symfony developers and #webdev community! Are you constantly battling those frustrating Access-Control-Allow-Origin CORS errors, especially when dealing with OPTIONS preflight requests from your frontend? You're not alone! The common pitfall is that OPTIONS requests often arrive without any payload or route parameters, causing Symfony's router (and especially #[MapRequestPayload]) to fail before CORS headers can be applied. Instead of reaching for a heavy bundle, here's a professional, lightweight solution: an Event Listener. By implementing a CorsSubscriber on the KernelEvents::REQUEST event with a high priority (e.g., 9999), you can intercept all OPTIONS requests right at the start of the Symfony lifecycle. This listener can then construct an immediate HTTP 200 response, inject the necessary Access-Control-Allow-* headers, and prevent further processing (like routing or DTO mapping). This approach ensures your API sends the correct CORS signals to the browser, unblocking your frontend operations. It's a clean, performant, and framework-native way to achieve full CORS compliance. For a full code example, detailed explanation, and best practices, check out the complete guide on my site: https://agconsulting.altervista.org/symfony-cors-risolvere-errore-options/  ( 6 min )

A while ago in a technical interview I got asked: “Can you walk me through how authentication and authorization actually work under the hood?” And like many devs I knew just enough to plug in Auth0/NextAuth etc… but not enough to explain the “why” behind the flow. This series is the version I wish I had back then — plain English, no magic ✨, just a mental model that sticks. Because the frontend knows nothing about you.

Ever clicked through your web app on multiple browsers and noticed something looked slightly off—or worse, a feature didn’t work at all? That’s why cross-browser testing is essential. Users expect your app to work seamlessly on Chrome, Firefox, Safari, Edge, and even some legacy browsers. Any hiccup can affect user experience, trust, and ultimately your business. The good news? Open source testing tools make this process a lot easier. By automating browser tests, you can quickly spot inconsistencies and ensure your app behaves the way it should—without spending hours manually checking each browser. Why Cross-Browser Testing Makes a Difference? Modern web apps are complex, and different browsers interpret HTML, CSS, and JavaScript in slightly different ways.

Most people in IT have at least heard of assembly language. Some even saw it during university - just enough to know it exists, but not enough to use it for anything real. Assembly used to be the secret behind high-performance code. Games like Quake, graphics engines, and device drivers often had big chunks written in assembly for one simple reason: speed. But times changed. Modern developers rarely touch assembly anymore, and for good reasons. Until recently, it simply didn't make sense for most projects. Well, at least, that's what I thought - until I tried something on my Mac a few days ago.

One of the key challenges in a food delivery service is ensuring that orders reach customers quickly while minimizing courier idle time (the time when they're online but without an active order). It seems simple: a customer places an order, the restaurant prepares it, and all that's left is to find the nearest available courier and send them to pick up the food. However, in reality, it's much more complex. In this article, I'll explain how we select the optimal courier for each order and how our approach has evolved over time.

Introduction When I am handling processes that can be a heavy load on my server, I like to create a sort of queuing system to handle each process one by one, so that if there is a chance of the server being overwhelmed, this can help prevent it. This kind of system can be used on both the client side and the server side. Today's blog, I am going to do a quick guide on how I set up a basic queue system for an application, one that focuses on dealing with them one by one and another that batches them in groups. To get started on the queue system, you can use functions or a class. But for today, I am going to use a class to demonstrate, but to make a function version, you are just splitting up the work into smaller bite-sized code. So first, we are going to create a class called QueueSyst…  ( 9 min )

Java Try-With-Resources: Your Ultimate Guide to Clean & Leak-Proof Code Let's be real for a second.

In August 2020, nearly 40% of A-level students in England saw their grades downgraded by an automated system that prioritised historical school performance over individual achievement. The algorithm, designed to standardise results during the COVID-19 pandemic, systematically penalised students from disadvantaged backgrounds whilst protecting those from elite institutions. Within days, university places evaporated and futures crumbled—all because of code that treated fairness as a statistical afterthought rather than a fundamental design principle. This wasn't an edge case or an unforeseeable glitch. It was the predictable outcome of building first and considering consequences later—a pattern that has defined artificial intelligence development since its inception.

Transit Gateway (TGW) is a service that connects multiple VPCs and on premises networks using a single gateway. Before Transit Gateways if you had multiple VPCs that needed to talk to each other, you had to create multiple peering connections. Each connection required manual routing, was non-transitive and hard to scale. TGW solves this by acting as a regional layer 3 router which provides transitive connectivity between attached VPCs, centralised control over routing and propagation, and can scale to thousands of VPCs. TGW Attachments are the connections between the TGW and the VPCs or VPNs. Each attachment represents a link between a specific VPC or VPN and the Transit Gateway, allowing for efficient traffic routing. Without attachments the TGW doesn’t even know those VPCs exist. A TGW by default has one route table and all other attachments use this for table for routing decisions. Routes are propagated from the attachments. A route table can contain static routes, propagated routes automatically learned from attachments that you enabled to propagate into this table and blackhole route with “blackhole = true” to drop matching traffic and prevent specific paths. TGW makes a routing decision based on the route table associated with the ingress attachment. This means that traffic entering from Attachment A will look at A’s associated route table to decide where to send the packet next. Return traffic will look at the returner’s associated table to avoid asymmetric routing. An association binds one TGW route table to an attachment and determines which route table a connection (attachment) uses. That table governs egress from that attachment and you can re-associate an attachment to a different TGW route table at any time. Propagation lets an attachment advertise its network prefixes into a TGW route table automatically so other attachments associated with that table can reach it without manual static routes. You turn propagation on per attachment per TGW route table.  ( 7 min )

🚀 A Glimpse Into the Future of Browsing You know that feeling when technology just works — like pure magic? So, I thought, what if I asked AI to do everything for me? Talking to My Browser I opened Comet and typed this into Perplexity: “Open YouTube, find the official NASA Moon landing video and jump to the moment Armstrong says ‘one small step for man.’” All that — without me touching the keyboard again. 🤯 🌐 Why This Is So Impressive This moment really hit me. 🧩 What Makes Comet + Perplexity Special Here’s why this little experiment blew my mind: Contextual Understanding Perplexity understood what I meant, not just what I said.

You’ll understand instantly why people are calling Comet the future of human–AI interaction.  ( 9 min )

The last time I felt like a programmer, people who wrote programs called themselves that (not Devs). So, hi. A long time ago, I didn't finish my computer science training. I wanted to make software when I grew up ... but, I never did. For clarity, this was a long while ago. Some time shortly after the Millennium bug didn't end the world, but before the first internet bubble had properly burst. It was around a time when the mini-disk was the best piece of technology known to man (and, fwiw, imo, it perhaps still is).

Let's be honest: playing with large language models is amazing, but seeing that OpenAI API bill at the end of the month can be... painful. 😅 I've been working with the GPT-4 and GPT-3.5 APIs a lot, and I noticed how quickly the costs can spiral out of control. A simple task routed to GPT-4 by mistake, an inefficient prompt, or running the same query over and over—it all adds up. I kept thinking there had to be a smarter, more automated way to manage this without rewriting all my code. That's why I built CostLens, a simple SDK I'm hoping can help other developers who are facing the same problem. At its core, CostLens is a drop-in SDK that automatically helps you cut your AI costs.

In today’s fast-moving digital landscape, your applications are the front door to your customers, your brand’s reputation, and your revenue. If an app is slow, buggy or down, you don’t just lose time; you lose trust and business. That’s why implementing strong Application Performance Monitoring (APM) is no longer optional. Application Performance Monitoring (APM) refers to the suite of tools, processes and instrumentation that track how your business applications perform, how they respond under real-user load, where bottlenecks exist, and why problems occur. Rather than waiting for users to complain or outages to happen, APM gives you visibility into the inner workings of your apps from the front-end request through back-end services, databases and external calls. In short: it’s how you …  ( 8 min )

Hi everyone! I'm a developer, and for my latest project, I built a minimalist typing test app called keydrift.com. It was a great experience, and I wanted to share a few things I learned, especially about using Firebase and Vite together. How I Built a Real-time Typing App with Firebase and Vite Vite: For the super-fast front-end build. Firebase Authentication: To handle user sign-ups and logins (including Google Sign-In). Firestore: To store all the user results and power the "Arena" leaderboard. One Cool Thing I Learned Then, on the Arena page, I use a Firestore query to fetch the top 50 scores, sorted by WPM and then accuracy. Because it's Firebase, it's fast and updates in real-time.

In today’s fast-paced software world, logging often gets treated as an afterthought—a few lines sprinkled here and there before a release. But when a production incident strikes at 3 AM, those logs become your North Star ✨ for making sense of chaos. After years in backend engineering and incident response, it’s clear: logging isn’t just about recording events—it’s about building observability into your system from day one. 💡 Research shows developers spend up to 35–50% of their time debugging issues. And a big chunk of that time is wasted digging through incomplete logs or trying to guess what really happened. In production, where you can’t just “add a print statement,” logs become your system’s black box 📦 Consider the real-world impact: Faster incident fixes: Teams with great logs reso…  ( 7 min )

Introduction In today’s world, almost every app you use — from Netflix to Spotify — runs on AWS (Amazon Web Services). But how does AWS actually work behind the scenes? The AWS Flow Explained The AWS architecture is built on a client-server-cloud model. Client This is where everything starts. The client can be: A web browser, A mobile app, or Any IoT device sending a request. The client sends a request (like logging in, fetching data, or uploading a file) to AWS servers. AWS Cloud Layer This is the core of the process. EC2 for computation (running servers and apps), S3 for storage, RDS for database management, Lambda for serverless execution. The AWS Cloud acts as the brain — managing scalability, security, and speed automatically. Database & Application Layer Here, the actual data and logic live: Database: Stores your user information, transactions, etc. Application Layer: Runs your backend code, APIs, or microservices. Both layers work together to process your request efficiently and securely. Network Layer Once AWS has processed everything, the results are sent back through its high-speed global network. User Finally, the user sees the response — maybe a webpage, dashboard, or streaming content — all delivered instantly thanks to the AWS global infrastructure. Why AWS Flow Matters Understanding this flow helps you design scalable and fault-tolerant systems. You can optimize how your app connects to the cloud. You learn to separate computation, storage, and networking for performance. You get a clearer idea of where services like CloudFront, Route53, or IAM fit in. Developer Takeaway AWS isn’t just hosting — it’s an entire ecosystem that powers millions of apps. AWS makes cloud computing simple — but understanding how its flow works internally gives you a professional edge. Whether you’re building a small portfolio project or an enterprise-grade app, knowing this structure helps you think like a cloud architect.  ( 7 min )

Artificial Intelligence (AI) is evolving beyond single, monolithic models. Today’s most capable systems are made up of multiple AI agents. This new paradigm of multi-agent systems (MAS) represents the next step in AI evolution, where collaboration and coordination between agents matter as much as individual intelligence. In this article, we’ll break down what multi-agent systems are, how they work through real-world analogies, and explore the different architectures that make them scalable and effective in practice. With the rapid development of Large Language Models (LLMs), many systems are now built around an LLM core (ChatGPT, Claude, LLaMA, etc.) and extended with prompts, functions, or pipelines to perform specific tasks. These systems are known as LLM Agents. There are several types …  ( 12 min )

App Store: link Most productivity tools push output. They want more tasks, more deadlines, more alerts. Clarity does not come from doing more. It comes from knowing what deserves attention. I like the Getting Things Done (a book about getting things done) idea of capturing everything so the mind can relax. I wanted a quieter way to do that. Mind Backlog is my take on GTD: capture, clarify, choose, and move on with less noise and more care. Think of your thoughts like a lightweight sprint board. Ideas, questions, and unsolved problems live here. Backlog is not failure. It is permission to let something rest until you are ready. Items you are tackling in this sprint. You decided they are solvable now or worth your energy today. Resolved or released. The goal is not endless checkboxes. The goal is to release mental load. You write what is on your mind. The app asks one question: Can I solve this right now? If yes, send it to What's the next Task. If not, let it rest in Backlog. Can I name the next action? If yes, send it to Active. If not, we will keep it warm in the Backlog. No due dates. No streaks. No pressure. Just a simple flow that helps you think clearly and act with intention. This is not a task grinder. It is a thought organizer. It helps you notice what is calling for attention, sort what is actionable, and let the rest breathe until you are ready. Sometimes the best productivity tool is not the one that makes you do more. It is the one that helps you think better.  ( 6 min )

The Rose’s Whisper: ADC as the Listener 🥀 On his tiny planet, the Little Prince kneels by his rose, her petals trembling. “What’s wrong?” he asks, but her voice is a soft sigh—a voltage too faint for his notebook (microcontroller) to read.

The ear hums, sorting her whispers into numbers: 36.2°C—Thirsty, but brave ✨. “How?” the prince asks. The ear chuckles: “I’m a SAR ADC—like you guessing her favorite water amount: ‘Is it 10ml?’ ‘No, 5ml?’ Until I find the truth.” Nearby, a Sigma-Delta ADC (a fox-eared device) sits, patient: “I listen longer,” it says, “like the fox waiting to be tamed—hearing every quiver, even the quiet ones.” The rose smiles: “Finally, so…  ( 8 min )

Every team has that one person, or two, who insists that “frontend tests are a waste of time.” They might say E2E tests are flaky, or that QA already does the job. But deep down, skipping tests isn’t a bold time-saving move; it’s a long-term productivity trap. Here’s how to win the argument (and save your project from endless regressions). Frontend changes are deceptively simple. You tweak a component or update an API call, and suddenly the login form stops working. Having automated tests for critical flows (login, checkout...) ensures that your app’s core functionality never silently breaks. Without tests, the real testers are your users, and they’re the worst kind of testers. Fixing a bug found in production takes exponentially more time than catching it during development. Manual QA can…  ( 7 min )

While other databases out there might shard, CouchDB is one of the few that does it automatically and saves you the annoying — read error-prone — work of setting it up yourself. Being unique in this way, it’s a topic you may not know too well. The arcane-sounding term (especially if it reminds you of the prismatic variety) doesn’t need to conjure confusion or intimidation. In this post, we’re going to take a deeper look at scaling CouchDB with shards: what sharding is, plus why and how to do it. Any given central processing unit (CPU) — the thing on which your database lives — has a physical limit to how much processing it can do at one time. By extension, there’s a limit to how big your database can get if you still want to do useful things with it if it can only run on a single core. D…  ( 15 min )

In some of the previous blogs, I wrote a lot about the IoT platform from Total.js. Like what it is, why it can be useful, how to install individual parts to get it working, and how to set it up and start using it. But there is still one part of the platform that has to be created or modified especially for your case. And those are drivers. We published some of the custom drivers we used before, but now we have added universal drivers. These drivers are ready to use. We created universal drivers for the electrometer, weather, meteo data, and switch. In this blog, I will introduce them to you. You can use them as they are, create new drivers based on principles used in these drivers, or modify them for your case. Also, I will show you how to add a sensor to one of them, so you will be able t…  ( 10 min )

Introduction In general you would want to deploy infrastructure using terraform, build and push docker images in CI/CD phase. But let's say, just in case, someone pointed a gun at your head asking you to build and push docker images from within Terraform, how would you do it? Fear not, I am here, let me save you today. It's simple, we will just wait check for file change - where a specific Dockerfile is kept, if any changes are detected we will build the image and push it. You have to have aws cli configured (v2 is prefered but v1 will just do) Terraform installed (I am using 1.5.5) So this will be our directory structure - . ├── src │ └── frontend │ ├── Dockerfile │ └── index.html └── Terraform ├── ecr.tf ├── main.tf └── variables.tf Here, we have a very basi…  ( 9 min )

🧠 Lexical Scoping and Closures — Ever seen a function in JavaScript remember a variable even after it's done running? That’s not magic — it’s Lexical Scoping and Closures. Let’s break it down with real-world analogies, demos, and how the industry uses it. Lexical Scoping means: "Variables are accessible based on where they are written in the code — not where they are called." Imagine your house has rooms. If you leave your phone in the living room, you can use it there. But if you go to the kitchen, you can’t use your phone unless you bring it with you. Same with code — variables live in their scope (room). Functions can access variables in their room and the rooms outside — but not inside other rooms. function outer() { const message = "Hello from outer!"; function inner() {…  ( 7 min )

Stage 1 of the HNGi13 QA Track focused on reviewing requirement documents and translating them into an actionable test plan. For this task, I worked on Gradific, a grading and task management platform for educators. My goal was to understand how features like workspace creation, assignment setup, and grading flow together, and then design a testing strategy around them. I started by analyzing the PRD and FRD, identifying core functionalities and edge cases. From there, I created a structured Test Plan outlining objectives, scope, approach, risks, and deliverables. I also designed 10 detailed test cases to validate and verify that the requirements are met and the system works as expected. This experience taught me how important it is to plan before testing commence, understanding requirements deeply helps uncover gaps early and ensures focused, efficient testing. Key Takeaway Translating requirements strengthens both product understanding and tester intuition. HNGi13 #QA #SoftwareTesting #HNGInternship #TestPlanning #QualityAssurance #BugDetective  ( 6 min )

In today’s fast-paced business world, organizations are constantly juggling countless communications, projects, and data streams. From Slack messages to emails, meetings, and shared documents, the sheer volume of information can overwhelm even the most organized teams. Yet, the most successful organizations operate like a finely tuned organism. Their secret? A “nervous system” that connects people, information, and workflows seamlessly. In this blog, we explore how building the nervous system of your organization can transform productivity, collaboration, and decision-making. Without a nervous system: Knowledge gets siloed in private chats or individual heads Every conversation, file, and decision is captured and connected Too many tools fragment information. Teams switch between Slack, email, Trello, and Google Drive, losing time and focus. Centralizing communication into one intelligent workspace ensures that: Conversations are linked to tasks, decisions, and files Automatically extract action items from meetings and messages Step 3: Connect Teams to Expertise Match questions or problems to team members with relevant skills Step 4: Make Data Actionable Convert conversations into searchable knowledge Step 5: Foster a Culture of Transparent Communication Encourage teams to share context instead of hiding it in DMs Why Nexy is the Nervous System Your Organization Needs Capture and store every conversation, file, and decision Conclusion Address — Company Name — Nexy Location — Netherlands  ( 8 min )

Abstract We introduce the Beta-Rho Orthogonality (BRO) score, a novel metric that quantifies the consistency between systematic risk exposure (beta) and correlation in cryptocurrency markets. Unlike traditional metrics that treat beta and correlation as separate measures, the BRO score reveals structural market relationships by examining their ratio. We demonstrate that this simple formulation serves as a multi-purpose analytical tool for: (1) detecting regime stationarity, (2) identifying tradeable structural relationships, (3) classifying predictability, and (4) constructing market-neutral portfolios. Our framework reveals four distinct behavioral regimes in crypto markets and provides a quantitative basis for distinguishing between manageable volatility and unmanageable chaos.

When Kotlin was announced as an official language for Android in 2017, I didn’t rush to learn it. Java felt familiar, and I didn’t see the point in switching. Then one weekend, I tried rewriting a small project in Kotlin. Suddenly, everything was cleaner. No more endless boilerplate. Null safety built right in. Functional features that just worked. I didn’t just like Kotlin—I wanted to use it everywhere. That was my turning point. And I’ve seen the same story play out with countless devs. Kotlin starts as “the thing Android makes you use” and ends up becoming your favorite language. Fast forward to 2025: Kotlin is no longer just about Android. It’s powering full-stack apps with Ktor, showing up in Spring projects, and even being used in multi-platform codebases.

Microsoft’s decision to end support for Windows 10 isn’t just another software update—it’s a declaration: Your device is no longer yours to control. Millions of machines, still powerful and capable, are now deemed obsolete, not because they’ve broken down, but because a corporation decided their time was up. This isn’t just an ecological scandal; it’s a reminder that when you buy a computer, you’re not truly buying freedom. You’re entering a lease agreement, where the terms can change—or terminate—without your consent. What if you could use your hardware for as long as it lasts, without arbitrary restrictions or forced upgrades? That alternative exists, and it’s called Linux.

I’m excited to announce that three of my UI designs were showcased during the Appian Community’s UX Design Lab | Mobile & Responsive Design livestream! 🎉 Seeing my work highlighted alongside so many creative and thoughtful submissions was an amazing experience. The session, hosted by Christine Danzi and Jennifer Higa, focused on the principles that make Appian applications not just functional — but intuitive, responsive, and user-friendly across all devices. Building for responsiveness goes beyond scaling layouts. Here are some of the core insights shared during the session that every Appian designer should keep in mind: Ensure that essential information remains visible and accessible on smaller screens without overwhelming the user. Design navigation structures that feel natural for mobile interactions — like bottom tabs or collapsible menus. Buttons, links, and interactive components should have ample spacing for easy tapping and accessibility. Use Appian’s dynamic layouts and conditional visibility to modify component behavior based on device size. Always test your designs on different screen widths to ensure consistent experiences across mobile, tablet, and desktop. Here’s a quick look at the responsive UI submissions that were featured in the livestream: A huge thanks to Christine Danzi and Jennifer Higa for hosting such an engaging session and providing valuable feedback on making Appian designs truly responsive. Events like these highlight the power of community learning — where every designer, developer, and contributor helps push the boundaries of what’s possible in low-code UX design.  ( 8 min )

Optimistic Superposition: A Quantum Leap for AI? The dream of truly intelligent AI hinges on our ability to train complex models, a process currently bottlenecked by sheer computational cost. Imagine training a model not in weeks or months, but in hours. What if we could explore solution spaces previously deemed intractable? This is where "optimistic superposition" comes in. At its core, it's a novel algorithmic approach designed to handle complex problem-solving by strategically delaying computationally intensive calculations. Instead of immediately tackling every possible scenario, the algorithm makes optimistic assumptions, carries these assumptions as constraints, and only resolves them when absolutely necessary. This "wait-and-see" approach drastically reduces the initial computati…  ( 7 min )

GitHub Home I remember a few years ago, I was leading a team to develop a real-time stock ticker dashboard. 📈 Initially, everyone's enthusiasm was incredibly high. We were all excited to build a "live" application with our own hands. But soon, we found ourselves stuck in the mud. The tech stack we chose performed reasonably well for ordinary REST APIs, but as soon as WebSockets came into the picture, everything became unrecognizable. Our codebase split into two worlds: the "main application" that handled HTTP requests, and a "separate module" that handled WebSocket connections. Sharing state between these two worlds, like a user's login information, became a nightmare. We had to resort to some very clever (or rather, ugly) methods, like using Redis or a message queue to synchronize data. …  ( 10 min )

Honestly, before I started this benchmark, I never imagined the performance differences would be this dramatic. As a junior computer science student, I always thought framework selection was mainly about features and ecosystem, and performance was just, well, good enough. That changed last month when our lab's project started crashing under load, and my advisor asked me to investigate which framework we should actually be using. That evening in my dorm room, setting up the test environment, my roommate laughed and said, "Are you becoming a performance engineer now?" I didn't think much of it at the time. I just figured if we're going to choose, we should choose something solid. What I discovered through testing surprised me in ways I didn't expect. Let me back up to our lab project. We wer…  ( 15 min )

1. Background This update introduces three new operators: pack-fields, log-to-metric, and metric-to-metric, which significantly optimize the conversion link from raw logs to structured data and then to time-series metrics. These improvements not only significantly enhance the efficiency of data processing but also provide broader application prospects for fields such as observability analysis and time-series prediction. • pack-fields: As an evolved form of e_pack_fields, it constructs JSON objects through intelligent field aggregation, achieving extreme compression of data density. • log-to-metric: As an inheritor of e_to_metric's core functionality, it converts unstructured logs into the gold standard format of time-series databases in a more elegant manner. • metric-to-metric: As a tool…  ( 10 min )

🧠 What is a Database A database is an organized collection of data stored so it can be easily accessed, managed, and updated by software or users. Think of it like a digital filing system — instead of paper folders, you have tables and rows. Example Let’s say you build a website for a school: The database stores students, teachers, and grades. The web app sends queries like: SELECT name, grade FROM students WHERE id = 1; The database engine (like MySQL) processes this query and returns results. Main Types of Databases Type Description Examples Relational (SQL) Data stored in tables (rows & columns) MySQL, PostgreSQL, Oracle, SQL Server Non-Relational (NoSQL) Flexible document or key-value storage MongoDB, DynamoDB, Redis Cloud Databases Managed by cloud providers AWS…  ( 8 min )

Read the original article：Reading Custom JSON Files in HarmonyOS Using getRawFileContent Context A developer is trying to read an intarray.json resource defined in a HarmonyOS project. They initially attempted to use the getStringArrayValueSync API from the ResourceManager but found it ineffective for accessing raw JSON data. Description The developer encountered difficulties retrieving a custom intarray.json file using typical resource manager methods intended for string or array resources. This file does not follow the standard element resource format (e.g., string, string-array) and thus requires a different approach for access and parsin Solution / Approach Instead of using getStringArrayValueSync, the correct method is: Place the intarray.json file into the resources/rawfile directo…  ( 7 min )

Introduction At Lingo.dev, I write a lot of TypeScript code. I'm definitely not a wizard, but I do try to play with features that go beyond the basic types. This post describes a number of features (and when you might want to use them) to help you expand your knowledge beyond the absolute fundamentals. as const assertions By default, arrays and objects are mutable, and TypeScript widens literal values to their general types. This makes it harder for TypeScript to help you catch bugs and provide accurate autocomplete. const colors = ["red", "green", "blue"]; // Type: string[] - could be any strings colors.push("yellow"); // Allowed, might not be what you want type Color = (typeof colors)[number]; // string (too general!)

Beyond Binary RAG: Enhancing Decision-Making with Nuanced Risk Assessment The all-too-familiar Red, Amber, Green (RAG) system has become a staple in risk management and decision-making processes across various industries. However, an over-reliance on this binary approach can lead to oversimplification of complex issues, resulting in inadequate risk assessment and suboptimal decision-making. The Problem with Binary RAG The traditional RAG system categorizes risks into three distinct states: Red: High-risk or critical situations that require immediate attention. Green: Low-risk or stable situations that require minimal attention. Amber: Medium-risk or uncertain situations that require monitoring. While this system provides a basic framework for risk assessment, it often fails to capture the nuances of complex issues. The binary nature of RAG can lead to: False negatives: Critical risks being overlooked due to their classification as Amber. **... This post was originally shared as an AI/ML insight.

The debate surrounding AI-powered ad personalization has sparked concerns about the potential loss of cultural diversity and creativity in advertising. On one hand, AI algorithms can analyze vast amounts of data to create highly targeted and effective ad campaigns that resonate with specific audience segments. However, this may lead to a homogenized consumer experience, where people are shown the same ads repeatedly, reinforcing existing biases and limiting exposure to diverse perspectives. To mitigate this risk, AI-powered ad personalization can be designed to foster cultural diversity and creativity in advertising. Here are a few strategies: Diverse data sources: Implement data collection methods that actively seek out diverse perspectives, such as partnering with community organizations, social media groups, or cultural influencers. This ensures that the AI algorithm is exposed to a wide range of experiences and viewpoints. Inclusive modeling: Use AI models that p... This post was originally shared as an AI/ML insight.

Many challenges in AI products stem less from choosing frameworks and more from how user experience (UX) and architecture shape each other. I first noticed this while using ChatGPT to draft and maintain product requirement documents (PRDs) — reusing prompt variants, manually curating context, and constantly tweaking outputs to stay aligned. The workflow technically worked, but it felt brittle and overly manual. That experience raised a question: What might it take for an agentic workflow — a coordinated system of specialized LLM sub-agents orchestrated by code rather than a single prompt — to produce and maintain a complex artifact like a PRD without so much manual prompting, context oversight, and guesswork? More broadly, how could changes in architecture and UX design improve usability,…  ( 13 min )

🧠 Introduction: A New Way to Code Is Emerging For decades, coding has meant writing lines of code manually—debugging, optimizing, and maintaining them over time. But in 2025, a new wave of development is rapidly transforming that model: Vibe Coding. Vibe Coding is an AI-first programming paradigm where developers describe what they want, and intelligent agents handle much of the code generation. Instead of spending hours crafting functions line by line, engineers focus on high-level logic, problem framing, and iterative refinement. This isn’t just another “no-code” trend—it’s a fundamental shift in how we build software. At its core, Vibe Coding means: Developers express intent in natural language or structured prompts. AI agents generate, refactor, and optimize code automatically. The …  ( 8 min )

Presented by Arm A simpler software stack is the key to portable, scalable AI across cloud and edge. AI is now powering real-world applications, yet fragmented software stacks are holding it back. Developers routinely rebuild the same models for different hardware targets, losing time to glue code instead of shipping features. The good news is that a shift is underway. Unified toolchains and optimized libraries are making it possible to deploy models across platforms without compromising performance. Yet one critical hurdle remains: software complexity. Disparate tools, hardware-specific optimizations, and layered tech stacks continue to bottleneck progress. To unlock the next wave of AI innovation, the industry must pivot decisively away from siloed development and toward streamlined, e…

Every seasoned Rails developer remembers the first time they opened a mature codebase. You navigate through the familiar models/, controllers/, and views/ with a sense of order.

Or a chaotic pile of Notifiable, Taggable, SoftDeletable, and ThatThingWeNeededForTheMarketingReport? This folder is more than just a directory; it's a Rorschach test for your application's architecture.

This week, I implemented a new feature for our beekeeping management platform 🐝: deduct the sold amount from the batch table and record the sale in a separate sold_honey table — atomically. At first, I planned to try doing this with two Supabase SDK calls: await supabase.from('honey_batches').update(...); await supabase.from('sold_honey').insert(...); But then I realized the problem — What if the first succeeds but the second fails? 😬 So I thought a lot and finally discovered a better way: Supabase RPC (Remote Procedure Call). I wrote a Postgres function (sell_honey()) that: Locks the batch row (FOR UPDATE) to prevent race conditions Validates available stock Deducts weight from the honey batch Inserts a record into sold_honey Runs all of this in one transaction — if anything fails, it…  ( 7 min )

In this blog, we will explore methods in Java, their types, and the best practices for writing efficient methods. A method in Java is a block of code that performs a specific task. It is defined using a specific structure that includes a name, return type, parameters (optional), and method body. access_modifier return_type method_name(parameter_list) { // Method body (logic to be executed) return value; // (Only required if return_type is not void) } Use our …  ( 12 min )

For the longest time, I kinda felt like a fraud. I'd browse LinkedIn, Threads, Instagram, X, Dev.to and all sorts and see posts like "I built a full-stack AI app in a weekend!" I'd listen to colleagues talk about their elaborate side projects. The unspoken message was clear: a real developer codes for fun. A real developer is always learning the next thing, always building. And I... wasn't. After eight hours of solving problems, writing code, and staring at a screen, the last thing I wanted to do was more of the same. I'd force myself sometimes, opening my laptop with a sense of dread, only to produce low-quality code and feel even worse. I thought this meant I wasn't "passionate" enough. I thought I was falling behind. Then, I hit a wall. I was stuck on a gnarly backend problem for days. …  ( 8 min )

In this project, we explored model evaluation metrics using a Lead Scoring dataset. The goal was to identify which factors most influence lead conversion and evaluate how well our model can predict them. Below are the key concepts and lessons learned throughout the assignment. A lead scoring model helps businesses identify which leads (potential customers) are most likely to convert. By assigning a score to each lead, sales teams can focus their efforts where it matters most — improving conversion rates and efficiency. In our dataset, the target variable (converted) indicates whether a lead converted (1) or not (0). The features included data such as: lead_score number_of_courses_viewed interaction_count annual_income Before modeling, we performed crucial preprocessing steps: Handling Miss…  ( 7 min )

Every great application begins with a simple, honest object. It does its job, it tells the truth, and it asks for little in return. It’s the UserService that fetches data, the Image that renders itself, the API that returns a response. But as our systems grow from humble scripts to sprawling architectures, this honesty becomes a liability. A naïve UserService can buckle under a million requests. A direct Image load can freeze a UI. A raw API call can be a gaping security hole. We need a guardian. A diplomat. An illusionist. We need the Proxy Pattern. This isn't just another Gang of Four entry.
